Why Are Asians More Prone to Stomach Cancer? Carcinogenic Habits You Should Know!

Anal cancer is a relatively rare form of cancer, and the types of tumours in the anus are more complex due to their location at the junction of the inner and outer layers of the embryonic tissues. Anal cancer typically originates from the tissues around the anus, including the anal skin, anal canal, or the mucous membrane inside the anus.

Bone cancer can be divided into primary and metastatic, which refers to cancer that has spread from other parts of the body to the bone tissue. The majority of cases fall under metastatic bone cancer. As for primary bone cancer, it originates in the bone cells and is relatively rare.

Bladder cancer is a type of cancer that develops in the cells inside the bladder, which is a hollow organ that stores urine. Most bladder cancers originate from the epithelial cells lining the inner walls of the bladder, known as transitional cell carcinoma (also called urothelial carcinoma). Many bladder tumours resemble small mushrooms, initially appearing on the surface layer of the bladder lining as papillary tumours. These tumours typically grow within the bladder lining initially, but over time, they may spread into the bladder's muscle wall and other parts of the body.
