Invasive breast carcinoma (not otherwise specified) is the most common type of breast cancer. It starts in the cells lining the ducts of the breast and invades surrounding breast tissue. This type of cancer is often referred to as invasive ductal carcinoma. It is the most common form of breast cancer. The diagnosis of invasive …

Encapsulated papillary carcinoma is a type of breast cancer that is usually non-invasive. Non-invasive means that the cancer cells are confined to the ducts where they started and have not spread into the surrounding breast tissue. This type of tumor behaves in a similar way to ductal carcinoma in situ (DCIS), another non-invasive form of …

Invasive apocrine carcinoma is a type of breast cancer. This type of breast cancer is made up of large pink cells that resemble the cells typically found in apocrine-type sweat glands in the skin. Invasive apocrine carcinoma is a rare type of cancer, representing approximately 1% of all breast cancers. What are the symptoms of …

Paget’s disease is a non-invasive type of breast cancer that involves the nipple and surrounding skin. It is considered non-invasive because the tumour cells are limited to a layer of the skin called the epidermis. Most tumours are believed to start in channels called ducts that run from the nipple to glands deep in the breast. …

A borderline phyllodes tumor is an uncommon breast tumor that arises from the stroma (supportive connective tissue) within the breast. It has characteristics that fall between benign (non-cancerous) and malignant (cancerous) phyllodes tumors. Borderline phyllodes tumors grow faster and have a greater likelihood of recurrence than benign tumors, but they typically do not spread to …

Invasive mammary carcinoma is a diagnosis used to describe a cancerous tumour in the breast that has not been subclassified into a more specific type of breast cancer. Additional tests often result in the tumour being subclassified as invasive ductal carcinoma or invasive lobular carcinoma. Is invasive mammary carcinoma a type of breast cancer? Yes. …

Invasive ductal carcinoma with apocrine features is a type of breast cancer. This type of breast cancer is composed of large, pink cells that resemble the cells typically found in apocrine-type sweat glands in the skin. Invasive ductal carcinoma with apocrine features is a rare type of cancer, representing approximately 1% of all breast cancers. …

Secretory carcinoma is a rare type of breast cancer that usually grows slowly and has a good prognosis. It is called secretory carcinoma because the tumor cells produce material known as secretions, which can be seen inside the cells and in the spaces between them when examined under a microscope. Secretory carcinoma can occur in …

The Nottingham histologic grade (or modified Scarff-Bloom-Richardson grade) is a system pathologists use to evaluate breast cancer under the microscope. It helps determine the aggressiveness of the cancer and provides important information for planning treatment. The grade is based on how different the cancer cells look from normal breast cells and how quickly they are …

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 …
