Breast Cancer

If you have breast cancer, then you know that it can have a devastating effect on both you and you family. Here we'll try to provide basic information about breast cancer and it's forms, symptoms and effects not eh body.

Breast cancer is cancer that forms in the cells of the breasts. There are numerous types of breast cancer, but cancer that begins in the milk ducts (ductal carcinoma) is the most common type.

After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States. Breast cancer can occur in both men and women, but it's far more common in women.

Public support for breast cancer awareness and research funding has helped improve the diagnosis and treatment of breast cancer. Breast cancer survival rates have increased and the number of deaths has been declining, thanks to a number of factors such as earlier detection, new treatments and a better understanding of the disease.

Signs and symptoms of breast cancer may include:

• A breast lump or thickening that feels different from the surrounding tissue
• Bloody discharge from the nipple
• Change in the size or shape of a breast
• Changes to the skin over the breast, such as dimpling
• Inverted nipple
• Peeling, scaling or flaking of the nipple or breast skin
• Redness or pitting of the skin over your breast, like the skin of an orange

When to see a doctor

Although the majority of breast changes don't turn out to be cancer, make an appointment to see your doctor if you find a lump or other change in your breast. Even if you've just had a mammogram with normal results, it's still important to have your doctor evaluate any changes.

Diagnosing breast cancer

Tests and procedures used to diagnose breast cancer include:

• Breast exam. Your doctor will check both of your breasts, feeling for any lumps or other abnormalities. Your doctor will likely check your breasts in varying positions, such as with your arms above your head and at your side.
• Mammogram. A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer. If an abnormality is detected on a screening mammogram, your doctor may recommend a diagnostic mammogram to further evaluate that abnormality.
• Breast ultrasound. Ultrasound uses sound waves to produce images of structures deep within the body. Your doctor may recommend an ultrasound to help determine whether a breast abnormality is likely to be a fluid-filled cyst or a solid mass, which may be either benign or cancerous. Breast ultrasound is helpful to guide radiologic biopsy to get a sample of breast tissue if a solid mass is found.
• Removing a sample of breast cells for testing (biopsy). A biopsy to remove a sample of the suspicious breast cells helps determine whether cells are cancerous. The sample is sent to a laboratory for testing. A biopsy sample is also analyzed to determine the type of cells involved in the breast cancer, the aggressiveness (grade) of the cancer and whether the cancer cells have hormone receptors.
• Breast magnetic resonance imaging (MRI). An MRI machine uses a magnet and radio waves to create pictures of the interior of your breast. Before a breast MRI, you receive an injection of dye. This test may be ordered after a breast biopsy confirms cancer, but before surgery to give your doctor an idea of the extent of the cancer and to see if there's any evidence of cancer in the other breast.

Other tests and procedures may be used depending on your situation.

Staging breast cancer

Once your doctor has diagnosed your breast cancer, he or she works to establish the extent (stage) of your cancer. Your cancer's stage helps determine your prognosis and the best treatment options. Complete information about your cancer's stage may not be available until after you undergo breast cancer surgery.

Tests and procedures used to stage breast cancer may include:

• Blood tests, such as a complete blood count
• Mammogram of the other breast to look for signs of cancer
• Chest X-ray
• Breast MRI
• Bone scan
• Computerized tomography (CT) scan
• Positron emission tomography (PET) scan

Not all women will need all of these tests and procedures. Your doctor selects the appropriate tests based on your specific circumstances.

Breast cancer stages range from 0 to IV, with 0 indicating cancer that is very small and noninvasive. Stage IV breast cancer, also called metastatic breast cancer, indicates cancer that has spread to other areas of the body.
