Mucinous Carcinoma Breast

This is a rare form of invasive cancer that starts in the milk duct and spreads to the nearby tissues in its advanced development stage. Colloid Carcinoma is also known as the colloid carcinoma and its tumor is made up of abnormal cancer cells that float within a pool of mucin, which later becomes part of tumor.

Recent research has revealed this kind of cancer is very rare in men and only 2 to 3 percent of invasive breast cancers can be Colloid carcinoma, meaning that it is the only type of breast cancer present within a tumor. This cancer can be diagnosed at any age but it mostly tends affect women who have gone through their menopause; women in their 60s or early 70s to be to more precise.

Despite colloid carcinoma being a invasive breast cancer, it tends to be less aggressive compared to other types of breast cancers since it responds well to treatment and also less likely to spread to lymph joints like other breast cancers.

Symptoms of Mucinous Carcinoma breast

Just like any other type of breast cancers, Colloid carcinoma does not cause any notable symptom, however, a lump may grow large enough that it can be felt when doing own self breast examination, Colloid carcinoma average size is about three centimeters, it can be larger or smaller.

Diagnosis of Colloid carcinoma breast

Its diagnosis involves combination of steps that include:

  1. Physical examination - A doctor may feel the lump in the breast or can be felt during self examination.
  2. Mammogram - A screening mammogram can detect Mucinous carcinoma by locating the cancer tumor and checking any evidence of cancer in the other areas in the breast. The lump detected usually looks like a non cancerous breast lump with well defined edges that push against healthy tissues nearby.
  3. Ultrasound - This involves use of sound waves to obtain the photograph of the breast tissue.
  4. Biopsy - This involves making small cuts to take out tissues sample from the area suspected to contain cancer cells for examination under microscope. This is the best and most accurate method of diagnosis of colloid carcinoma because other diagnosis can not differentiate between Mucinous carcinoma breast cancer and other types of breast cancer.


Pure Mucinous carcinoma is less likely to spread to other auxiliary parts of the body, meaning that it will require less treatment compared to other types of invasive breast cancers. Here are some of the treatment plans for this cancer:

  1. Surgical removal of the cancer - This can be either, lumpectomy, where the surgeon removes pert of the breast containing the tumor or total maectemy, which involve removal of the beast without the removal of lymph nodes.
  2. Adjuvant therapy - It can be chemotherapy, radiation therapy or hormonal therapy. If you have under gone a lumpectomy, it is usually followed by a radiation therapy to destroy any remaining cancer cells. Hormonal therapy usually involves taking medication like tamoxifen, an estrogen inhibitor since most of Mucinous carcinoma is estrogen receptor positive thus tamoxifen is likely to effect the treatment.
