CBD for Cervical Cancer

What is Cervical Cancer

Cervical cancer is a type of cancer that forms in the cells of the cervix, with the cervix being a hollow cylinder that connects the lower part of a woman’s uterus to her vagina. Most cervical cancers begin in cells on the surface of the cervix and is one of the leading causes of death in American women.

It is thought that various strains for the human papillomavirus (HPV), a sexually transmitted infection, are one of the key factors that play a role in the development of most cervical cancers. This is because, when some women are exposed to the HP virus, and despite the immune system trying to prevent the virus from doing harm, in some women, the virus survives for years. This often contributes to a process in which this causes some cervical cells to become cancerous, causing cervical cancer to develop.

The risk of developing cervical cancer can be reduced by having regular pap-smears, a screening test that check for cervical cancer cells. In addition, women should use condoms during sex, and can receive a vaccine, both of which that protects against HPV infection that can reduce the risk of cervical cancer.

Cervical Cancer Types

There is more than one kind of cervical cancer and includes:

Squamous cell carcinoma
Refers to cancer cells that form in the lining of your cervix and is found in up to 90% of cases.

Adenocarcinoma:
Refers to cancer cells that form in the cells that produce mucus.

Mixed carcinoma
Features a combination of squamous cell carcinoma and adenocarcinoma.

After a diagnosis of cervical cancer, the treating physician will assign the cancer a stage. The stage classification indicates whether the cancer has spread, and if so, how far. It will also help in determining the correct treatment protocols.

Cervical cancer has four stages:

Stage 1: The cancer is small and localized. It hasn’t spread to other parts of your body.

Stage 2: The cancer is larger and may have spread outside of the uterus and cervix and/or to the lymph nodes. However, it still hasn’t reached other parts of your body.

Stage 3: The cancer has spread to the lower part of the vagina and/or to the pelvis, and may also be blocking the ureters (the tubes that carry urine from the kidneys to the bladder). It hasn’t spread to other parts of your body.

Stage 4: The cancer has spread outside of the pelvis to other parts of body, and into organs like the lungs, bones, or brain.

Symptoms of Cervical Cancer

During the early stages of cervical cancer, there are often no symptoms present. During later stages, when the cervical cancer is more advance, the most common symptoms include:

Other symptoms (especially once it has spread) can include:

Cervical Cancer Medications & Treatments

The most common treatments for invasive cervical cancer are surgery and radiation therapy. Other common treatments include chemotherapy and biological therapy.

Pharmaceutical Interventions

Chemotherapy uses powerful drugs to kill cancer cells and are usually provided as an outpatient treatment as a hospital, doctor’s office, or even sometimes at the patient’s home. Oncologists primarily use it for cervical cancer that has advanced locally, or has spread to other parts of the body. Chemotherapy is applied in cycles of intensive treatment that are followed by periods of recovery.

Biological therapy or immunotherapy targets certain parts of the immune cells that are either turned on or off to trigger an immune response. This blocks a protein on the cells that shrink tumors and / or slow their growth.

Targeted drug treatments focus on specific weaknesses present within cancer cells and blocking these weaknesses using targeted drug treatments that can cause cancer cells to die. It is usually combined with chemotherapy and is often an option for advanced cervical cancer.

Non-Pharmaceutical Interventions

Surgery to remove cervical cancer cells can include:

Radiation therapy (or radiotherapy) is when high-energy rays are directed at the cervical cancer cells to damage them and stop their growth. As with surgery, the radiation affects cancer cells only in the treated area.

CBD and Cervical Cancer

Research & Scientific Evidence for using CBD during cervical cancer treatment

The clinical evidence for Cannabidiol (CBD) as a viable treatment option for Cervical Cancer is promising.

Cannabidiol Inhibits Cancer Cell Invasion Via Upregulation Of Tissue Inhibitor Of Matrix Metalloproteinases-1

In a 2008 study published in the journal of Biochemical Pharmacology, researchers investigated the potential role of tissue inhibitors (TIMPs) thought to be involved in the degradation of the matrix components of the microenvironmental spaces surrounding tumors that contribute to tumor cell metastasis and angiogenesis.

Using human cervical cancer and lung cancer cells, the study focussed on the potential role of TIMP up regulation in the anti-invasive action of CBD along with the possible involvement of cannabinoid receptors (CBRs), transient receptor potential vanilliod 1 (TRPV1) channels, mitogen-activated protein kinases (MPAKs) activation as well as cellular invasion of CBD in this process.

The study showed that CBD decrease cancer tumor cell invasiveness and identified a CBR and TRPV1 triggered expression of TIMPs as an important mediator of this process. They concluded that CBD provide a novel mechanism for inhibiting cancer cell invasion, making it a therapeutic option for the treatment of cancers like cervical cancer.

Inhibition of cervical cancer cell proliferation by cannabidiol

Similar to the above study, researchers from Kent State University’s Department of Biological Sciences investigated the anti-proliferative effect of CBD on the cervical cancer cell lines. They presented their research findings in 2016 at the 9th Joint Meeting of GA, ASP, AFERP, PSE, SIF & JSP in Copenhagen, Denmark.

Their results showed that CBD successfully inhibited the proliferation of cervical cancer cells while also inducing apoptosis (cell death) of nearly all cervical cancer cells within 24 hours of CBD exposure. In addition, within a few hours of treatment, the cells also exhibited features of paraptosis, an alternative form of cell death that scientist consider as an alternative death pathway, especially in apoptosis resistant cancer cells.

They concluded that the results of their study suggest that CBD exerts its anti-proliferative effect via multiple mechanisms and show potential as an effective treatment for cervical cancer.

Cannabidiol rather than Cannabis sativa extracts inhibit cell growth and induce apoptosis in cervical cancer cells

Finally, in another study from 2016 published in the journal BMC Complementary and Alternative Medicine, researchers compared the anti-proliferative effects of crude whole-plant extract of Cannabis sativa with CBD as a reference standard on different cervical cancer cell lines to asses the efficacy of each.

The results indicated that both the crude Cannabis sativa extract and CBD could reduce cancer cell viability and halt cell proliferation in three different cervical cancer cell lines. However, CBD also induced apoptosis which plays a motor role in the convolution of nuclear and cellular outlines, nuclear fragmentation, and cancer cell shrinkage.

They concluded that, although more research is needed, their data suggests that CBD, rather than crude Cannabis sativa extracts, prevent cell growth and induce cell death in cervical cancer cell lines. This makes CBD a novel potential cervical cancer therapy.

Anecdotal Evidence on using CBD for cervical cancer

Most anecdotal evidence relating to cannabinoids for treating cervical cancer revolves around cannabis as opposed to CBD. For instance, this woman from New Zealand claimed that cannabis oil cured her cancer, while this woman used THC and CBD to help battle the side effects she was experiencing with chemo.

CBD as a Complementary Treatment for cervical cancer

Most available evidence shows that CBD may complement cancer treatment, and that CBD may help people with cervical cancer by helping reduce pain and inflammation. In addition, many people suffering from cervical cancer also report having other side effects from chemotherapy treatment, including sleep problems, feelings of anxiety and depression.

In one large case series study investigating the effects of CBD on anxiety and sleep, the results show CBD helps improve sleep and/or anxiety in clinical populations. Similarly, CBD can further support cervical cancer patients by reducing stress, anxiety, depression while also helping to promote REM sleep that is thought to help improve overall mood.

Bottom Line

Scientific and anecdotal evidence both suggest that CBD can support cervical cancer patients, especially by helping to reduce chemotherapy-induced neuropathic pain, inflammation, nausea and vomiting. If you or a loved one are suffering from cervical cancer and want to try CBD, talk to your medical practitioner first. He or she can help put together a plan that includes CBD along with other treatment options to help you deal with your symptoms safely and effectively.
