Inflammatory breast cancer is an uncommon form of rapidly advancing breast cancer that usually accounts for approximately 1% to 3% of all breast cancer diagnoses. Inflammatory breast cancer is a form of invasive breast cancer that progresses quickly and should be differentiated by physicians from other forms of advanced breast cancer with similar characteristics. Inflammatory breast cancer causes the breast to appear swollen and inflamed. This appearance is often caused when cancer cells block the lymphatic vessels in the skin of the breast, preventing the normal flow of lymph fluid and leading to reddened, swollen and infect-looking breast skin—hence the designation "inflammatory" breast cancer. Inflammatory breast cancer is not caused by infection or inflammation as was once believed.

With inflammatory breast cancer, the breast skin has a thick, pitted appearance that is classically described as peau d’orange (resembling an orange peel). Sometimes the skin develops ridges and small bumps that resemble hives.

The three major parts of the brain control different activities:

• Cerebrum - The cerebrum is the largest part of the brain. It is at the top of the brain. It uses information from our senses to tell us what is going on around us and tells our body how to respond. It controls reading, thinking, learning, speech, and emotions.

The cerebrum is divided into the left and right cerebral hemispheres, which control separate activities. The right hemisphere controls the muscles on the left side of the body. The left hemisphere controls the muscles on the right side of the body.

• Cerebellum - The cerebellum is under the cerebrum at the back of the brain. The cerebellum controls balance and complex actions like walking and talking.
• Brain Stem - The brain stem connects the brain with the spinal cord. It controls hunger and thirst. It also controls breathing, body temperature, blood pressure, and other basic body functions.

What are benign and malignant brain tumors?

Brain tumors can be benign or malignant:

• Benign brain tumors do not contain cancer cells:
   
• Usually, benign tumors can be removed, and they seldom grow back.
• The border or edge of a benign brain tumor can be clearly seen. Cells from benign tumors do not invade tissues around them or spread to other parts of the body. However, benign tumors can press on sensitive areas of the brain and cause serious health problems.
• Unlike benign tumors in most other parts of the body, benign brain tumors are sometimes life threatening.
• Very rarely, a benign brain tumor may become malignant.

• Malignant brain tumors contain cancer cells:
   
• Malignant brain tumors are generally more serious and often are life threatening.
• They are likely to grow rapidly and crowd or invade the surrounding healthy brain tissue.
• Very rarely, cancer cells may break away from a malignant brain tumor and spread to other parts of the brain, to the spinal cord, or even to other parts of the body. The spread of cancer is called metastasis.

The symptoms associated with inflammatory breast cancer are usually the first cause of concern. These symptoms may include:

• breast redness
• swelling
• warmth
• ridges or pits in the breast skin (a condition referred to as peau d’orange; resembling an orange peel)
• a change in the size or shape of the breast
• nipple discharge or an inverted (pulled back) nipple
• swollen lymph nodes

Inflammatory breast cancer can sometimes be mistaken by patients and physicians as a breast infection (or mastitis) because its symptoms , and the rapidity with which they appear (sometimes within weeks) resemble those associated with infections. However, while most breast infections will respond to antibiotics, inflammatory breast cancer will not. In fact, symptoms of inflammatory breast cancer do not usually get better or worse as infections do. If symptoms persist more than two or three weeks despite treatment, further testing and a breast biopsy should be performed to determine whether cancer is present.
