This is when they use a cold metal probe to freeze and kill abnormal cells.
If the surgeon finds cancer in the lymph nodes in the pelvis, they may remove the lymph nodes around the aorta as well. They will test to see how far cancer has spread, and radiation may be advised if cervical cancer has become aggressive.
Your cervix is a cylinder-shaped area of tissue that connects the uterus and the vagina. The area that can be seen through the vagina during pelvic exams is called the ectocervix, and the tube that goes through the cervix is called the endocervix. There is an overlapping border between the ectocervix and the endocervix called the transformation zone.
This is when they send a laser through the vagina to vaporize abnormal cells.
When testing in test tubes and Petri dishes, they found that cannabidiol and cannabis sativa L both stopped the cancer cells from dividing and spreading as well as killing off the cancer cells. They also noted that cannabidiol was more effective than the cannabis sativa L plant which contains THC.
Right now, no. There is no evidence that CBD oil can cure cancer.
All drugs and dietary supplements are regulated by the FDA. But as long as CBD oil is not marketed as a medicine or a dietary supplement, producers can get around that policy. So right now, CBD oil is very unregulated. That means it’s hard to know how much CBD or THC is really in any given product. Certain hemp CBD products have been found to contain significantly less CBD or more THC than advertised.
What is CBD oil, and how does it differ from marijuana and hemp?
It’s hard to say if CBD oil can alleviate cancer symptoms or cancer treatment side effects, because the studies are pretty mixed and even fewer are standardized.
At the national level, any product of marijuana — including CBD — is still technically illegal when used medically. Although the 2018 Farm Bill legalized the production of hemp nationally, that’s only permitted if it’s not marketed for medical use or as a dietary supplement. CBD products intended for medical use should undergo an FDA review process.
Representative cell viability bar graphs of cervical cancer cell lines. MTT assay was conducted to determine IC50 following incubation of SiHa, HeLa, and ME-180 cells with different doses of butanol extract (a, b, c), hexane extract (d, e, f), and cannabidiol extract (g, h, i) for a period of 24 h. Data was expressed as mean value ± standard deviation (SD). The level of significance was determined using Students t-Test with ns representing p > 0.05, ***represents p < 0.001, **represents p < 0.01, and *represents p < 0.05
Since Adenosine 5’-triphosphate acts as a biomarker for cell proliferation and cell death, an ATP assay was conducted. This was done in order to determine whether Cannabis sativa and cannabidiol deplete ATP levels in cervical cancer cells. SiHa, HeLa, and ME-180 cells were treated at different time points, between 2 and 24 h. ATP levels were first detected after 2 h. In general, ATP depletion was cell type dependent. In HeLa cells treated with the crude extracts from butanol and hexane, ATP was significantly reduced by 74 % (from 627621 to 164208 RLU) and 78 % (from 627621 to 133693 RLU) respectively. While with SiHa there was reduction of 31 % (from 4719589 to 3221245 RLU) and 22.5 % (4719589 to 3655730 RLU) respectively (figure). Whereas in ME-180 there was no change between treatments and untreated. Similar results were observed in cannabidiol treated cells. At 2 h, treatment with IC50 led to a reduction in ATP levels by
Cell growth analysis
From the apoptosis experiments conducted, it is clear that the mode of cell death induced by cannabidiol and extract of Cannabis Savita was that of apoptosis. However, we needed to confirm whether the type of apoptosis induced is it p53 dependent or independent as it is well known that p53 is mutated in many cancers. Protein expression of RBBP6, Bcl-2, Bax and p53were performed and results recorded. In butanol extract p53 was significantly increased in SiHa and HeLa cells while remaining unchanged in ME-180. Similar results were observed in hexane treated cells. In all cell lines the level of p53 negative regulator in cancer development was reduced by all treatment.
We first determined whether Cannabis sativa extracts and cannabidiol possess anti-proliferative effects using MTT assay. MTT assay determines IC50, which represents the half maximal concentration that induces 50 % cell death. Cannabis sativa extracts were able to reduce cell viability and increase cell death in SiHa, HeLa, and ME-180 cells. These results correlate with the findings obtained by , whereby they reported reduced cell proliferation in colorectal cancer cell lines following treatment with Cannabis sativa. According to [7, 24, 25] Cannabis sativa extracts rich in cannabidiol were able to induce cell death in prostate cancer cell lines LNCaP, DU145, and PC3 at low doses (20–70 μg/ml). It was suggested that cannabidiol might be responsible for the reported activities. Therefore, in this study, cannabidiol was included as a reference standard in order to determine whether the reported pharmacological activities displayed by Cannabis sativa extracts might have been due to the presence of this compound. For positive extract inhibitory activity, Camptothecin was included as a positive control. Camptothecin functions as an inhibitor of a topoisomerase I enzyme that regulates winding of DNA strands [19, 20]. This in turn causes DNA strands to break in the S-phase of the cell cycle . A study conducted by , exhibited the ability of camptothecin to be cytotoxic against MCF-7 breast cancer cell line and also induce apoptosis as a mode of cell death at 0.25 μM. We also observed a similar cytotoxic pattern, whereby camptothecin induced cell death in HeLa, SiHa, and ME-180 cells, however, at a much higher concentration.
Cervical cancer remains a burden for women of Sub-Saharan Africa. Half a million new cases of cervical cancer and a quarter of a million deaths are reported annually due to lack of effective treatment . Currently, the recommended therapeutic regimens include chemotherapy, radiation therapy, and surgery. However, they present several limitations including side effects or ineffectiveness . Therefore, it is important to search for new novel therapeutic agents that are naturally synthesized and cheaper, but still remain effective. Medicinal plants have been used for decades for health benefits and to treat several different diseases . In South Africa, over 80 % of the population are still dependent on medicinal plants to maintain mental and physical health . However, some of the medicinal plants used by these individuals are not known to be effective and their safety is still unclear. It is therefore important to scientifically evaluate and validate their efficacy and safety. In the present study, cervical cancer cell lines (SiHa, HeLa, and ME-180) were exposed to different concentrations of Cannabis sativa extracts and that of its compound, cannabidiol, with the aim of investigating their anti-proliferative activity.
