Invasive apocrine carcinoma is a rare type of breast cancer. Although it starts from epithelial cells normally found inside the ducts and glands in the breast, the tumour is made up of large pink cells that resemble the cells normally found in apocrine-type sweat glands in the skin.

Background: A borderline phyllodes tumour is a type of breast tumour that shows uncertain behaviour over time. While most borderline phyllodes will behave like a non-cancerous tumour over time, a small number will spread to other parts of the body in a manner more in keeping with a cancerous tumour. What are the symptoms of …

Background: A benign phyllodes tumour is a rare type of breast tumour. It is classified as a fibroepithelial tumour because it comprises both “fibrous” and “epithelial” elements. It’s part of a spectrum of tumours known as phyllodes tumours, which can also be malignant (cancerous) or borderline (having features between benign and malignant). Benign phyllodes tumours …

Invasive ductal carcinoma with apocrine features is a rare type of breast cancer. Although this type of cancer starts from epithelial cells normally found inside the ducts and glands in the breast, the tumour is made up of large pink cells that resemble the cells normally found in apocrine-type sweat glands in the skin. Another …

Sclerosing adenosis is a non-cancerous growth made up of small glands in the breast. The glands are surrounded by a type of connective tissue that resembles a scar. When large enough, this type of growth can be seen in imaging studies such as mammography, and a biopsy may be performed to rule out cancer. What …

Pseudoangiomatous stromal hyperplasia (PASH) is a non-cancerous growth in the breast. It is made up of specialized cells called myofibroblasts. The growth is called “pseudoangiomatous” (which means “like blood vessels”) because the myofibroblasts form small slit-like spaces that look similar to blood vessels when examined under the microscope. What causes PASH? PASH appears to be …

Invasive mucinous carcinoma is a type of breast cancer where the tumour cells are surrounded by a thick fluid called mucin. To be called mucinous carcinoma, at least 90% of the tumour needs to be made up of mucin. Compared to the more common invasive ductal carcinoma, invasive mucinous carcinoma is more likely to develop …

Phyllodes tumour is a rare type of breast tumour. Most phyllodes tumours will behave like non-cancerous tumours. However, a small number (approximately 10%) will behave like cancer. This behaviour includes the ability to spread through the normal tissue in the breast and to other parts of the body. The entire tumour must be removed surgically …
