BRCA2:

How does brca2 cause breast cancer?: Brca2 mutations insert or delete nucleotides in the gene. They disrupt protein production from one copy of the gene in each cell and resultsin a defective version of the brca2 protein. This defective version is unable to repair damaged DNA or fix any mutations in other genes. It allows the cells to further grow and multiply uncontrollably, which can then form a tumor.

What does breast cancer do to the human body and organs?: Cancer can metastasize to other organs throughout the body. Depending on where the tumor is, it can alter the body image. Tumors can grow and interfere with digestive, nervous, and cirulatory systems. It can also release hormones that can alter the body function. The cancer cell itself can move throughout the body using blood or lymph systems and destroy healthy tissue.

Major Symptoms and what life is like with disorder: - bloody discharge from nipple- thickening or swelling of all or part of breast (even if no lump is felt)-skin irritation or dimpling- pain in any part of breast-redness, flakiness, scaliness, or thickening-nipple retraction-lump in or near breast or under armAlthough there are many possible symptoms, people suffering breast cancer may not even show syptoms, especially in the early stages. People living with this disorder may need to suffer a lot of pain. They must be treated and regularly attend chemotherapy or some form of therapy.

Treatments: -Surgery - used to remove tumor (breast-conserving surgery or mastetomy)-Radiation - high-energy rays or particles that destroy cancer cells -Chemotherapy - treatment with cancer-killing drugs that travel through the bloodstream to get to the cancer cells-Hormone therapy - lowers amount of estrogen in the body and blocks action of estrogen on breast cancer cells -Targeted therapy - drugs that target specific characteristics of cancer cells

How disorder is inherited: Cancer risk is inherited depending on the gene involved. Mutations in the BRCA1 and BRCA2 genes are inherited in an autosomal dominant pattern. People don't actually inherit the disease itself, though. The increased risk of the disease is what is inherited.
