Breast Cancer: Benign And Malignant

Cancer is a disease of mitosis that removes the stop points on the mitosis cell and keeps building many cells. It starts with a single cell which transforms into a cancer cell. When the cell turns into a cancer cell, it forms a mass group of cancer cells called a tumor. Different cancer cells forms different cancers.
The p53 gene is usually to control the cell cycle ,but it is most often mutated in over 50 percent of all cancers. The BRCA1 gene is to help suppress the tumor formation, but if it gets mutated, then a tumor will often form. BRCA1 is often associated with breast cancer. The two types of tumors are Benign and Malignant. Benign tumors often stay near the original site while Malignant tumors send signals out to produce a new blood vessel near the tumor site. …show more content…
They can divide forever if they are supplied with enough resources. They are not density dependent so they don’t stop when they filled up one layer. Density dependent is when the cells are dividing and they cover a surface. They then stop. Cancer cells wouldn’t do this. Normal cells would often fill up the bottom of a bucket compared to if it had cancer, it would fill the entire bucket and just stack on top of each other. Cancer cells also often have an abnormal amount of chromosomes. Cancer spreads because they have an abnormal cell surface and this allows it to break apart and spread to neighboring cells. This is most important for cancer to spread. The spreading of cancer cells is called
