Cervical cancer is a serious health problem around the world, especially in poor and developing areas where the disease is often diagnosed late, leading to high death rates. Although current treatments have helped improve survival, they can cause strong side effects and sometimes stop working due to drug resistance. Natural plant compounds such as curcumin, withaferin A, piperlongumine, piperine, resveratrol, and baicalein have shown good anticancer effects. They help by causing cancer cells to die, stopping cancer spread, and controlling important pathways like NF-?B, Akt, JAK/STAT, and HPV E6/E7. However, these compounds do not dissolve well and are poorly absorbed in the body, which limits their medical use. Therefore, modern drug delivery systems like nanoparticles and solid lipid nanoparticles (SLNs) are needed to improve their effectiveness. Overall, herbal medicines show good potential as supportive treatments for cervical cancer, but more clinical studies are still required.
Cervical cancer continues to be a major and widely occurring malignancy among women worldwide., with its impact being particularly severe In developing and middle-income nations [1] . The epidemiological burden is especially significant in India [2] , where an estimated 122,844 women are newly diagnosed each year and approximately 67,477 die from the disease [3] . India has the highest rate of cervical cancer in South Asia, with about 22 cases per 100,000 women. This is higher than Bangladesh (19.2), Sri Lanka (13), and Iran (2.8) [4] . In countries such as Mexico, cervical cancer leads to the death of more than 4,000 women annually, underscoring the urgent need to improve therapeutic strategies, particularly for cases identified at locally advanced stages [5] . Cervical cancer typically originates in the lower portion of the uterus, at the junction where it meets the vagina. The disease progresses through several distinct stages, as illustrated in (Fig. 1) [6] . The heaviest burden is observed in Sub-Saharan Africa, where insufficient screening, low awareness, and lack of proper healthcare contributes to high disease and death rates [7].
Fig.1: Stages of cervical cancer [6]
In 2020, India accounted for approximately 21% of newly diagnosed global cervical cancer cases and 23% of related deaths [8] . Over 120,000 women develop the disease each year in the country, and more than 75,000 lose their lives due to delayed screening and inadequate early detection [9] . Persistent infection with high-risk HPV, particularly HPV-16 and HPV-18, is the leading cause of cervical cancer[10] . Because early-stage disease often presents with minimal or no symptoms, regular screening techniques such as Pap smears and HPV DNA testing are essential for timely diagnosis [11] . At the molecular level, cervical cancer involves dysregulation of pathways controlling inflammation, cell proliferation, and survival [12] . Anti-apoptotic proteins such as Bcl-2 become overexpressed, whereas pro-apoptotic proteins including Bax and caspases (3, 8, 9) are suppressed. This imbalance enables cancer cells to resist programmed cell death [13] . Additionally, angiogenic mediators such as VEGF support tumor growth and promote vascularization [14] .
Pathophysiology of cervical cancer are :-
Step 1: HPV Infection : HPV enters cervical epithelial cells through minor abrasions or sexual contact and attaches to surface receptors such as heparan sulfate [15,16] .
Step 2: Viral Replication : The viral DNA moves into the cell nucleus, and proteins E1 and E2 help manage its replication[17,18] .
Step 3: Integration and Oncogenesis : The viral DNA joins the host DNA, causing high levels of E6 and E7 proteins that turn off tumor-fighting proteins p53 and Rb, leading to uncontrolled cell growth and cancer[19–21] .
Step 4: Immune Evasion : HPV-infected cells evade immune detection by suppressing immune responses and downregulating MHC class I and II molecules [20,22,23] .
Step 5: Angiogenesis and Metastasis: Tumor cells stimulate new blood vessel formation and invade surrounding tissues, eventually spreading to distant organs [24,25] .

Cervical cancer affects multiple organ systems beyond the cervix itself [26] . As the disease advances and treatments such as chemotherapy, radiotherapy, or surgery are administered, patients often experience additional health issues known as complications or comorbidities. These complications may arise either directly from tumor growth or as adverse effects of treatment modalities, frequently requiring further medical care [27,28] .
Table 2. Probable Causes of Cervical Cancer
|
Cause |
Explanation |
|
HPV infection |
Most common reason. It spreads during sex. HPV types 16 & 18 cause 70% of cases [10] |
|
Lack of HPV vaccination: |
Girls who don’t get the HPV vaccine early are at higher risk of getting infected later in life [31] |
|
Smoking |
Increases the risk of cervical cancer by damaging cervical cells and lowering immune defence [11] |
|
Genetic predisposition |
If close relatives had cervical cancer, the chances are slightly higher for you too [11] |
|
Poor genital hygiene |
Not keeping private parts clean can lead to infections and increase the risk of cervical cancer [11] |
Prevention and New Technologies :
Recent technological advancements have significantly improved cervical cancer prevention and early detection [29] . Visual Inspection with Acetic Acid (VIA) is becoming increasingly accessible and serves as a simple, low-cost, and reliable screening method suitable for primary healthcare settings [30,32] . ne major advantage of VIA is its ability to provide immediate results, facilitating a “see-and-treat” approach in which precancerous lesions are treated on the same day using cryotherapy, thereby improving patient compliance [32] . One major advantage is that VIA provides instant results, allowing same-day treatment of precancerous lesions with cryotherapy at the same facility. This “see-and-treat” approach enhances treatment adherence and reduces patient loss to follow-up [33] . Additionally, newer HPV vaccines administered to girls aged 9–14 offer strong protection against cervical cancer and represent a major public health advancement [34] .
CONVENTIONAL THERAPY OF CERVICAL CANCER :
Conventional therapy for cervical cancer refers to established, evidence-based treatment modalities that have been widely used and validated over time [35] . These therapies encompass surgery, radiation therapy, chemotherapy, and their combinations, tailored to the cancer's stage and individual patient factors [36] .
Definitive Chemoradiation (CRT) in Cervical Cancer :
For cervical cancer patients in FIGO stages IIB to IVA, chemoradiation is the main treatment. Studies show that adding cisplatin-based chemotherapy helps patients live longer, although it can cause short-term side effects like stomach problems and bone marrow suppression. However, it does not increase long-term side effects. At present, the standard treatment uses chemoradiation with weekly or every-three-week cisplatin, along with external beam radiation therapy and a brachytherapy boost.
Definitive Intensity-Modulated Radiation Therapy (IMRT) :
IMRT has been shown to improve outcomes for cervical cancer patients [39]. In a randomised study by Gandhi et al. (2021), 44 patients were assigned to receive either conventional three-dimensional radiation or IMRT, IMRT significantly reduced grade ≥2 acute GI toxicities and long-term GI problems [40] Some patients in this trial also had PET/CT scans to precisely outline functional bone marrow, helping to further reduce bone marrow suppression [41] . IMRT in these cases lowered severe neutropenia and GI toxicity compared to historical rates for example, when giving 45 Gy in 25 fractions to the whole pelvis and prophylactic lymph nodes, an additional boost of 55.0–57.5 Gy to involved nodes achieved high complete response rates on PET/CT after 3 months [42] . This SIB technique is now widely adopted, and the EMBRACE II study is actively evaluating IMRT and image-guided radiation therapy (IGRT) approaches with SIB for cervical cancer [43].
Image-Guided Radiation Therapy (IGRT) :
IGRT is important because it allows IMRT to deliver radiation very accurately, which helps protect nearby healthy tissues from damage. CBCT is the most commonly used technique in IGRT. Using CBCT images every day helps doctors correct patient positioning mistakes and reduces the need for large treatment margins [45] .
Proton Beam Therapy (PBT) :
A Japanese study of 25 cervical cancer patients treated with proton boost achieved excellent local control at five years — 100% for stage IIB and 61% for stage IIIB/IVA — and long-term survival rates of 89% and 40%, respectively [46] . Modern IMPT (intensity-modulated proton therapy) can deliver better cumulative doses to tumors while sparing healthy tissues compared to VMAT [47] . Dosimetric comparison studies between IMPT and IMRT have shown 20–40% improvement in bone marrow sparing [48] . Ovarian-sparing Therefore, brachytherapy remains the standard of care for locally advanced cervical cancer. Dosimetric studies have shown that PBT can significantly reduce radiation dose to both the small and large bowel while still delivering an optimal dose to the target tumor area [49,50] . This advantage is especially important when treating para-aortic lymph nodes, as PBT also lowers the dose to critical organs such as the kidneys and spinal cord [51] . Since whole pelvic radiation therapy can cause premature menopause in younger patients, a study evaluated ovarian-sparing IMPT versus volumetric modulated arc therapy (VMAT) [52,53] . The study found that all IMPT plans succeeded in sparing the ovaries, whereas on ly 40% of VMAT plans were able to achieve ovarian sparing [54] .
Several treatment plans have successfully achieved a mean ovarian dose (Dmean) below 15 Gy while maintaining adequate target coverage [55] . There is growing clinical evidence supporting the use of proton therapy for gynecological cancers [56] . One study reported outcomes for 11 women treated with pencil beam scanning intensity-modulated proton therapy (IMPT) after hysterectomy for gynecologic malignancies. The toxicity profile was favorable, with only one case of grade 3 acute gastrointestinal toxicity and no grade 3 or higher genitourinary toxicities [57] . Ongoing prospective studies (e.g., NCT03184350) are investigating the role of proton beam therapy (PBT) for post-operative uterine and cervical cancers [58,59] . However, further research is needed to confirm the long-term oncological outcomes of PBT compared to IMRT-based treatments in larger patient populations.
Current Drugs For Cervical Cancer Treatment :
In early-stage cervical cancer, surgery can often cure the disease. Chemotherapy is mainly used for most other patients. For very small tumors (stage IA1) or small localized tumors (IB1 and IIA1), treatments like conization or hysterectomy can successfully cure the cancer. In more advanced stages, the usual treatment is radiation therapy combined with cisplatin-based chemotherapy. Other chemotherapy drugs, such as paclitaxel, vincristine, gemcitabine, and 5-fluorouracil, can improve the effect of radiation or work together with cisplatin to kill more cancer cells. However, using chemotherapy alone is not very effective in advanced cervical cancer[64] .
HERBAL MEDICINES USED IN THE TREATMENT OF CERVICAL CANCER:-
Curcumin in the Treatment of Cervical Cancer:- Curcumin, a naturally occurring polyphenolic compound derived from the rhizome of Curcuma longa (turmeric), has gained significant attention due to its broad-spectrum pharmacological activities and potent anticancer properties [65] . It is an orange-yellow crystalline compound with a slightly bitter taste, having the molecular formula C??H??O? and a molecular weight of 368.37 g/mol [66] (Fig. 2) . Curcumin has beneficial effects in many health problems, including inflammation, oxidative stress, metabolic diseases, and cancer. It shows anti-inflammatory, antioxidant, blood pressure–lowering, fat-reducing, antibacterial, liver-protective, and anticancer activities. Curcumin helps kill cancer cells by activating caspase-3 and caspase-9, which cause programmed cell death. It also blocks important proteins like NF-κB and AP-1 that play a major role in inflammation and cancer growth [69] (Fig 3) . Moreover, curcumin causes cell cycle arrest at the G2/M phase and enhances the production of reactive oxygen species (ROS), thereby promoting oxidative stress-mediated apoptosis in cervical cancer cells [70] . Animal model experiments further demonstrated tumor regression and enhanced apoptosis upon curcumin administration [71]. Additionally, when used in combination with standard chemotherapeutic agents such as cisplatin, curcumin enhances cytotoxic activity while reducing the side effects associated with chemotherapy [72] . These findings highlight its potential as a promising adjuvant in cervical cancer therapy [73] . However, despite its remarkable pharmacological benefits, the clinical application of curcumin is limited due to its poor aqueous solubility, low bioavailability, and rapid systemic metabolism [74] . To overcome these limitations, researchers are developing novel formulations such as curcumin-loaded nanoparticles, liposomes, and solid lipid nanoparticles (SLNs) to improve its stability, absorption, and therapeutic efficacy [75] . Thus, curcumin represents a valuable natural compound with promising potential in the prevention and treatment of cervical cancer, particularly when delivered through advanced nanocarrier systems [76] .

Resveratrol as a Herbal Medicine for the Treatment of Cervical Cancer :- Resveratrol is a naturally occurring polyphenolic compound that belongs to the class of phytoalexins [102] (Fig.8). It is mainly found in grapes, blueberries, peanuts, and red wine. Because it is plant-derived, resveratrol is considered a herbal compound, Various studies have demonstrated that resveratrol possesses strong anticancer potential against cervical cancer [103] . In cell-based (in vitro) and animal (in vivo) studies, resveratrol has been shown to suppress cancer cell growth, induce apoptosis, and arrest the cell cycle [104] . Although these findings highlight resveratrol as a promising herbal anticancer agent, its clinical use is still limited due to poor bioavailability [105,106]. Therefore, developing novel formulations such as nanoparticles, liposomes, or solid lipid nanoparticles (SLNs) could enhance its absorption and therapeutic effectiveness [107] . Overall, resveratrol can be regarded as a potent plant-based compound with significant potential for the herbal treatment and prevention of cervical cancer [108] .

Shù) in the Treatment of Cervical Cancer :- Camptotheca acuminata, commonly known as Xi Shu, is a medicinal tree whose bark and fruits contain potent anticancer alkaloids, primarily camptothecin (CPT) [120,121] (Fig.11) . To overcome its poor solubility and limited bioavailability, several camptothecin derivatives, such as irinotecan and topotecan, have been developed and are now widely used in chemotherapy for various cancers, including cervical cancer [122] . Clinical studies by the European Organization for Research and Treatment of Cancer (EORTC) evaluated irinotecan (350 mg/m² every three weeks) as a first-line chemotherapeutic agent for cervical cancer [123] . The study reported an overall response rate of 15%, with 24% of patients responding in non-irradiated regions (Group A), while no responses were observed in previously irradiated regions (Group B) [124]. However, adverse effects such as myelosuppression, diarrhea, and dehydration were noted, leading to a few treatment-related deaths. These findings indicate that, although camptothecin derivatives show significant therapeutic potential against cervical cancer, further research is required to reduce gastrointestinal toxicity and improve treatment safety [125,130] .

Several studies have also reported its hepatoprotective and liver-protecting activities. When the lyophilized mycelial powder of A [140] camphorata was dissolved in distilled water, it was found to be safe and non-toxic. In the context of cervical cancer, extracts of A. camphorata were shown to trigger apoptosis in HeLa and C-33A cell lines [141]. This apoptotic response involved activation of caspase-3, caspase-8, and caspase-9, along with increased cytochrome c release [142] . The extract also upregulated pro-apoptotic and upregulation of pro-apoptotic proteins such as Bad, Bak, and Bim [143] . The extract showed antiproliferative effects by inducing G2/M phase cell cycle arrest in cervical cancer cells [144] . Yng et al. demonstrated that treating HeLa and C-33A cells with A. camphorata extract (10–1000 µg/mL) reduced cell viability in a dose- and time-dependent manner as shown by the MTT assay [145,146] . Higher concentrations further increased activation of caspase-3, caspase-8, and caspase-9 and elevated cytosolic cytochrome levels [147] . Expression of Bak, Bad, and Bim increased, while levels of Bcl-2 and Bcl-xL were reduced at higher doses [150] . Overall findings indicate that A. camphorata activates both intrinsic and extrinsic apoptotic pathways and exhibits strong cytotoxic effects on cervical cancer cells [148] . Therefore, A. camphorata may be considered a promising phytotherapeutic or adjunct treatment candidate for cervical cancer [149] .

Lycopodium clavatum (Jin Bu Huan) :- Alcohol-based extracts of Lycopodium clavatum have been used to support the treatment of liver diseases and Alzheimer’s disease. Research has shown that this extract can protect mice from liver cancer–causing chemicals. In HeLa cervical cancer cells, lycopodine showed strong anticancer activity by causing changes in DNA structure, increasing cell death, breaking DNA into fragments, and activating caspase-3 [156,157] .
CONCLUSION
Herbal compounds show strong potential against cervical cancer by stopping cancer cell growth, inducing apoptosis, reducing metastasis, and supporting conventional treatments. Although their low solubility and bioavailability are challenges, advanced delivery systems like nanoparticles can improve their effectiveness. Overall, herbal therapeutics offer a safe and promising approach for future cervical cancer management.
