10 things you should know about cancer

What is cancer? To carry out body functions, our bodies need cells( tiny units of the human body). These cells grow and multiply to better perform most body functions. 

However, when these cells grow and multiply out of control, and in an abnormal manner, then they can form a tumor, which can be malignant (meaning the tumor is cancerous) or benign ( which means it’s a tumor but not cancerous).

What are the most common cancers in Kenya?

All body parts have cells, which means that cancer can start in any part of the body. Common causes of cancers in men include prostate cancer, esophageal cancer, Kaposi’s sarcoma, and in women cervical cancer, breast cancer, gastric/stomach cancer, and esophageal cancer.

IMPORTANT: with early diagnosis, there’s definitely going to be a good prognosis.

What is metastasis?

This basically means that cancer can spread from the originally affected part to other parts of the body, for example when cancer starts at the esophagus, it can metastasize to the lungs, it however does not then become lung cancer, but remains esophageal cancer. The name given to the type of cancer totally depends on the first affected part of the body and that is why as a patient or a caregiver, you must let your doctor explain the type of cancer you have in detail.

What causes cancer?

For many years now, research and studies have been done, but there is no specific cause that we can point our fingers at. However, we do have very many risk factors that can predispose us to various types of cancers. Some of the risk factors like smoking, taking too much alcohol, a lack of exercise, and poor eating habits are easily modifiable, others like age, gender, and family genetic history are non-modifiable. This, therefore, means that 

cancer is not a curse.

Can you inherit Cancer/ is cancer contagious?
