Causes and Risks Factors for Kaposi Sarcoma
Kaposi sarcoma is a type of cancer that develops from the cells lining the lymph or blood vessels. Kaposi sarcoma is caused by infection with a virus called human herpesvirus-8 (HHV-8), also known as Kaposi sarcoma-associated herpesvirus (KSHV). This virus infects the cells that line blood and lymph vessels, causing abnormal cell growth. The development of this cancer requires individuals with an HHV-8 infection to also have a weakened immune system.
It's important to note that not everyone with HHV-8 will develop Kaposi sarcoma, and it is more common in individuals with compromised immune systems, such as those living with HIV and Acquired Immunodeficiency Syndrome (AIDS).
Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors for Kaposi sarcoma include:
- Aging: Increasing age can weaken the immune system, increasing the risk of developing classic Kaposi sarcoma.
- Late-stage HIV: Having late-stage HIV is a significant risk factor for developing Kaposi sarcoma. When HIV is not well-controlled and antiretroviral treatments are not accessible or not taken, the risk of developing Kaposi sarcoma is significantly higher.
It's important to note that these non-modifiable risk factors cannot be changed or altered. They are factors that contribute to the development of Kaposi sarcoma but cannot be controlled by individual habits or lifestyle choices.
Modifiable risk factors are those that can be changed or controlled to reduce the risk of developing a certain condition. In the case of KS the modifiable risk factors include:
- Low CD4 levels: Low CD4 levels, which are a measure of immune function, are also a risk factor for Kaposi sarcoma. When CD4 levels are low, the risk of developing this type of cancer increases.
- HHV-8 infection: HHV-8 (Human Herpesvirus 8) is a virus that allows Kaposi sarcoma to develop.
- Living in endemic areas: People from equatorial Africa can lead to chronic infections and malnutrition, weakening the immune system and increasing the risk of endemic Kaposi sarcoma.
- Use of medication that weakens the immune systems
- History of organ transplant
To prevent or reduce the chances of getting Kaposi sarcoma, there are several actions a person can take to modify their risk factors. Here are some steps they can consider:
- Take antiretroviral drugs: Kaposi sarcoma primarily develops in people with weakened immune systems, especially those with HIV. Taking antiretroviral drugs can greatly reduce the risk of developing the cancer. These medications help control HIV and strengthen the immune system, making it less susceptible to Kaposi sarcoma.
- Maintain good HIV management: People with late-stage HIV are at a significant risk for developing Kaposi sarcoma. It is important to follow prescribed antiretroviral therapies and regularly consult with a healthcare provider to manage HIV effectively. By keeping the virus under control, the risk of developing Kaposi sarcoma can be mitigated.
- Get regular medical check-ups: Regular medical check-ups are crucial for early detection and treatment of any health issues, including Kaposi sarcoma. People who have late-stage HIV or any new health symptoms should contact a doctor promptly, as early diagnosis improves the outlook for treatment.
- Practice safe sex: Kaposi sarcoma is caused by a virus called HHV-8, which can be transmitted through sexual intercourse. To reduce the risk of acquiring HHV-8, it is important to practice safe sex by using barrier methods such as condoms. This is especially important for individuals with weakened immune systems, including those with HIV.
- Avoid sharing needles: People who use injectable drugs are at a higher risk of developing Kaposi sarcoma. To minimize this risk, it is important to avoid sharing needles or other drug paraphernalia. Using clean and sterile equipment can help prevent the transmission of HHV-8 and reduce the chances of developing this form of cancer.
Remember, these actions can help modify risk factors associated with Kaposi sarcoma, but it's always important to consult with a healthcare provider for personalized advice and guidance based on individual circumstances.
