How is cervical cancer spread?

Cervical cancer is primarily spread through the human papillomavirus (HPV), specifically high-risk HPV types. HPV is a group of related viruses that can infect the genital and other areas, as well as the mouth and throat. High-risk HPV strains, such as HPV-16 and HPV-18, are strongly associated with the development of cervical cancer.

Here is how cervical cancer is spread:

HPV Transmission: HPV is primarily transmitted through direct skin-to-skin contact, typically during sexual activity. This includes vaginal and as well as any form of genital-to-genital contact.

Asymptomatic Carriers: Many individuals infected with high-risk HPV types may not show any symptoms and are unaware that they are carriers of the virus. This makes it possible for the virus to be spread unknowingly to sexual partners.

Persistent Infection: In some cases, HPV infection can persist in the body for years without causing symptoms. During this time, the virus can gradually cause changes in the cervical cells that may lead to the development of cervical cancer over time.

Development of Precancerous Lesions: High-risk HPV infection can lead to the development of precancerous lesions in the cervix. These changes may progress to cervical cancer if not detected and treated.

Metastasis: In advanced stages, cervical cancer can spread to nearby tissues and lymph nodes. In rare cases, it may also metastasize to distant organs, such as the lungs, liver, or bones.

It's important to note that not all HPV infections lead to cervical cancer. In fact, most HPV infections resolve on their own, and only a small percentage progress to cervical cancer. Regular cervical cancer screenings, including Pap smears and HPV tests, can detect precancerous changes in the cervix and allow for early intervention and treatment, reducing the risk of cervical cancer. Additionally, vaccination against HPV is a highly effective preventive measure that can significantly reduce the risk of infection with high-risk HPV types and, consequently, the risk of cervical cancer.

How do you get cervical cancer?

Cervical cancer is caused by human papilomavirus virus, or HPV, usually spread through unprotected sex. It can inhibit in one's body without manifesting itself as symptoms.


Can cervical cancer spread to the liver?

Yes, cervical cancer can spread to the liver, although it's more common for it to metastasize to nearby lymph nodes or distant organs such as the lungs. When cervical cancer progresses to advanced stages, cancer cells may travel through the bloodstream or lymphatic system to the liver. This spread can lead to liver dysfunction and other complications, impacting the overall prognosis. Regular monitoring and early detection are crucial for managing such metastasis.


Can NuvaRing cause cervical cancer?

The studies suggest that it increases the risk of cervical cancer, and more cases of cervical cancer surfaced during the studies. However, they are labeled non-conclusive. I have personal experience, though. I have cervical cancer with a negative HPV test - meaning I do not have HPV but still managed to get cervical cancer. I used the NuvaRing just under a year ago. I have no other causes for it - I do not smoke, I am not overweight, I do not have a weakened immune system, etc. The only factor that I had was the NuvaRing. I am not sure how doctors go about linking a diagnosis with a cause but there is not a doubt in my mind that this was caused by the NuvaRing.

Can intercourse to a cancer patient cause cancer?

Yes, although it may not be comfortable for the woman. Cervical cancer can cause abnormal uterine bleeding, and can cause vaginal discomfort. It is important to know that cervical cancer is caused from HPV, which is a sexually transmitted virus. If a woman has cervical cancer, she should make certain to have protected sex when with a new partner so as not to spread the virus.
