Semester 2: Week 1- Cancer.

Cancer can develop when cells do not reach their Hayflick limit. They do not reach their Hayflick limit which is when cells stop dividing. This means that cancerous cells are constantly dividing. They keep going thru processes of mitosis. This means that lots of cells will develop. Cancer can also grow when the cells attach to veins and get glucose from these veins to increase their production. Chemotherapy stops processes like mitosis so cancer cells won't grow. There is a also a P53 tumor suppressor gene in our DNA that sometimes doesn't work.
