Breast cancer is the most common cancer in women, and the second leading cause of cancer death in women behind lung cancer. While breast cancer can occur at any age, it is more common in women over 40. Breast cancer can be diagnosed through a physical exam and mammogram, but it can also be diagnosed through tests that use radiation or chemotherapy.
What is breast cancer?
Breast cancer is a disease that occurs when cells in the breast grow out of control. The most common types of breast cancer are ductal carcinoma (the most common form), lobular carcinoma, and seminoma.
There are three stages of breast cancer: early stage, intermediate stage, and late stage. The treatments for each stage vary depending on the type and location of the cancer.
The risk factors for breast cancer include age, family history, obesity, and having been exposed to ionizing radiation (such as from the sun). breast cancer is treatable with surgery, chemotherapy, or radiation therapy.
Types of breast cancer
There are many types of breast cancer, but the most common is the ductal carcinoma. Ductal carcinomas are tumors that form in the milk ducts near the breast. They can be either invasive or non-invasive and can spread to other parts of the body.
Stage 1 breast cancer is the most common and is characterized by a lump, changes in breast size, or a change in nipple shape. Treatment typically includes surgery to remove the tumor and radiation therapy to destroy any remaining cancer cells.
Stage 2 breast cancer is more advanced and may have spread to other parts of the body. Treatment includes surgery to remove as much of the tumor as possible, chemotherapy to kill any remaining cancer cells, and radiation therapy to destroy any remaining cancer cells.
Stage 3 breast cancer has spread beyond the original tumor site and may not be treatable with traditional methods. Treatment may include surgery to remove part of the surrounding tissue, radiation therapy to destroy any remaining cancer cells, and chemotherapy if there are no other options.
Breast cancer stages
There are three main types of breast cancer: invasive, lobular and ductal. Invasive breast cancer is the most serious and can spread to other parts of the body. It accounts for about 50% of all cases of breast cancer. Lobular breast cancer is the most common type and is made up of small, irregularly shaped cells that may or may not have spread to other parts of the body. Ductal breast cancer is less common than lobular and invasive breast cancer, but is more aggressive and has a higher survival rate.
Each stage of breast cancer has different symptoms and treatments. The three main stages are:
1. Early-stage breast cancer (less than 1 cm in size)
2. Early-stage ductal carcinoma in situ (DCIS)
3. Late-stage breast cancer ( tumors greater than 1 cm in size)
Treatment for early-stage breast cancer typically includes surgery, radiation therapy, chemotherapy and hormone therapy. Treatment for DCIS may include surgery, radiation therapy or chemotherapy depending on the stage and risk factors for the tumor. Treatment for late-stage breast cancer usually includes surgery, radiation therapy or chemotherapy
Treatment for breast cancer
There is no one-size-fits-all approach to treating breast cancer, as the treatment plan will vary depending on the stage of the cancer, the individual’s age, health history and other factors. However, most breast cancer treatments involve surgery to remove the tumor, followed by chemotherapy and/or radiation therapy.
