Detecting breast cancer with non-invasive LED scanner

Thursday, June 29th, 2006

This report from PhysicsWeb.org covers a story about a new prototype optical scanner using near-infrared light-emitting diodes (LEDs) that can be used to detect early stage breast cancer. This promising device is safer than mammograms which uses X-rays. Near-infrared light is harmless to the human body at the levels that are required for this device. For those who are interested in the technical details, the abstract of the article was published in the Review of Scientific Instruments.

The Stages of Breast Cancer

Sunday, June 18th, 2006

The different stages of breast cancer, according to the American Cancer Society, indicate the size of a tumor and how far the cancer has spread within the breast, to nearby tissues, and to other organs. Specific treatment is most often determined by the following stages of the disease:

Stage 0 or Carcinoma in situ: Cancer is confined to the lobules (milk-producing glands) or ducts (passages connecting milk-producing glands to the nipple) and has not invaded nearby breast tissue.

Stage I: Tumor is smaller than or equal to 2 centimeters in diameter and underarm (axillary) lymph nodes test negative for cancer.

Stage II: Tumor is between 2 and 5 centimeters in diameter with or without positive lymph nodes, or tumor is greater than 5 centimeters without positive lymph nodes.

Stage III: This stage is divided into substages known as IIIA and IIIB:

  • IIIA: Tumor is larger than 5 centimeters with positive movable lymph nodes, or tumor is any size with lymph nodes that adhere to one another or surrounding tissue.
  • IIIB: Tumor of any size has spread to the skin, chest wall, or internal mammary lymph nodes (located beneath the breast and inside the chest).

Stage IV: Tumor, regardless of size, has metastasized (spread) to distant sites such as bones, lungs, or lymph nodes not near the breast.

Recurrent breast cancer: The disease has returned in spite of initial treatment.

You can find more information about the different stages of breast cancer also at the NCI website.

Breast Cancer Therapy

Friday, June 16th, 2006

This story from the Sun Sentinel reports on Dr. Judith Hurley’s treatment of breast cancer involveing a combination of two cancer drugs - cisplatin and docetaxel - with the biological agent Herceptin given over 12 weeks. In most cases, that combination shrinks the tumors dramatically, so that surgery can remove the rest. After three to six weeks of rest, patients get two more cancer drugs, doxorubicin and cyclophosphamide, followed by radiation.

Personalized Treatment Trial for Breast Cancer

Thursday, June 15th, 2006

The Trial Assigning IndividuaLized Options for Treatment (Rx), or TAILORx, was launched today to examine whether genes that are frequently associated with risk of recurrence for women with early-stage breast cancer can be used to assign patients to the most appropriate and effective treatment. TAILORx is sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), and is coordinated by the Eastern Cooperative Oncology Group (ECOG). All of the NCI-sponsored clinical trials groups that perform breast cancer research studies have collaborated in the trial’s development and are participating in this study.

Detecting Breast Cancer

Tuesday, June 13th, 2006

Breast changes occur in almost all women. Most of these changes are not cancer. However, some breast changes may be signs of cancer. Breast changes that are not cancer are called benign.

Lumpiness

Most women have some type of lumpiness in their breasts. Some areas may be more dense than others and can feel lumpy in an exam. What you are feeling may be glandular breast tissue.

Breast Changes Due to Your Period

Many women have swelling, tenderness, and pain in their breasts before and sometimes during their periods. You may also feel one or more lumps during this time because of extra fluid in your breasts.

Because some lumps are caused by normal hormone changes, your health care provider may suggest watching the lump for a month or two to see if it changes or goes away.

Single Lumps

Single lumps can appear at any time and come in various types and sizes. Most lumps are not cancer, but your health care provider should always check the lump carefully. He or she may do more tests to make sure the lump is not cancer.

Check with your health care provider if you notice any kind of lump. Even if you had a lump in the past that turned out to be benign, you can’t be sure that a new lump is also benign.

Nipple Discharge

Nipple discharge is common for some women. It is fluid that comes from the nipple in different colors or textures. Usually, it is not a sign of cancer. For example, birth control pills and other medicines, such as sedatives, can cause a little discharge. Certain infections also cause nipple discharge. However, for women who are going through or have passed menopause, nipple discharge can be a sign of cancer.

See your doctor if you have nipple discharge for the first time, or a change in your discharge’s color or texture. He or she may send a sample of the discharge to be checked at a lab.
