Any living creature- from homo sabians to our beloved pets can be afflicted with cancer. Cancer can show up on any internal organ and outside on the skin. There is damage to the genes that control cell division and growth. Cells become cancerous as a result of mutations. Cancer is not an infection.
No two cancers are alike. Your cancer is unique to you. It's your cells that become corrupt during the division process. The drugs available to treat cancer are mass produced to cover a blanket of cancers. Which is why some people may not be "cured" . They don't respond as favorable as others may. Ca cells are corrupt and vulnerable and cannot ward off virus's like normal cells.
Genetic damage accumulates over time which is why you see many cancers develop later in life. Environmental pollutants, hereditary factors, exposure to radiation and cigarette smoke will cause mutations. Cancerous cells grow into abnormal tissues known as masses.
When cancer cells spread through the body this is called metastasis. Any kind of cell can become cancerous. No one is immune.
