Invasive lobular carcinoma (ILC), sometimes called infiltrating lobular carcinoma, is the second most common type of breast cancer after invasive ductal carcinoma (cancer that begins in the milk-carrying ducts and spreads beyond it)

“invasive lobular carcinoma” refers to cancer that has broken through the wall of the lobule and begun to invade the tissues of the breast. Over time, invasive lobular carcinoma can spread to the lymph nodes and possibly to other areas of the body.

Although invasive lobular carcinoma can affect women at any age, it is more common as women grow older. According to the American Cancer Society, about two-thirds of women are 55 or older when they are diagnosed with an invasive breast cancer.

Some research has suggested that the use of hormone replacement therapy during and after menopause can increase the risk of ILC.

IDC Type: Cribriform Carcinoma of the Breast #Breast cancer Summit 2019

In invasive cribriform carcinoma, the cancer cells invade the stroma (connective tissues of the breast) in nestlike formations between the ducts and lobules.

Within a tumour, there are distinctive holes between the cancer cells, making it look something like Swiss cheese.

Invasive cribriform carcinoma is usually low grade, meaning that its cells look and behave somewhat like normal, healthy breast cells. In about 5-6% of invasive breast cancers, some portion of a tumour can be considered cribriform. Usually, some ductal carcinoma in situ (DCIS) of the cribriform type is present as well.

#IDC Type: Papillary Carcinoma of the Breast #Breast cancer Summit 2019

Invasive papillary carcinomas of the breast are rare, accounting for less than 1-2% of invasive breast cancers. In most cases, these types of tumours are diagnosed in older women who have already been through menopause. An invasive papillary carcinoma usually has a well-defined border and is made up of small, finger-like projections.

Often it is grade 2, or moderate grade, on a scale of 1 to 3 — with grade 1 describing cancer cells that look and behave somewhat like normal, healthy breast cells, and grade 3 describing very abnormal, fast-growing cancer cells. In most cases of invasive papillary carcinoma, ductal carcinoma in situ (DCIS) is also present. (DCIS is a type of cancer in which the carcinoma cells are confined to the breast duct.)

#Mucinous Carcinoma of Breast #Breast cancer Summit 2019

Mucinous carcinoma of the breast — sometimes called colloid carcinoma — is a rare form of invasive ductal carcinoma (cancer that begins in the milk duct and spreads beyond it into nearby healthy tissue). In this type of cancer, the tumour is made up of abnormal cells that “float” in pools of mucin, a key ingredient in the slimy, slippery substance known as mucus.

In mucinous carcinoma, however, mucin becomes part of a tumour and surrounds the breast cancer cells. Under a microscope, it looks like the cancer cells are scattered throughout pools of mucus. Although mucinous carcinoma can be diagnosed at any age, it tends to affect women after they’ve gone through menopause.

• A physical examination of the breasts. Your doctor may be able to feel the lump in the breast, or you may feel it yourself during a breast self-exam.
• A mammogram to locate a tumour and check for evidence of cancer in other areas of the breast. A screening mammogram often can detect a mucinous carcinoma, but it typically looks like a benign (non-cancerous) breast lump.
• Ultrasound uses sound waves to obtain images of breast tissue.
• MRI to obtain additional images of the breast and check for other areas of cancer.
• A biopsy involves making a small incision and taking out all of a tumour or using a needle to remove tissue samples from the suspicious area, for examination under a microscope.

IDC type: Medullary Carcinoma of Breast

Medullary carcinoma of the breast is a rare subtype of invasive ductal carcinoma (cancer that begins in the milk duct and spreads beyond it), accounting for about 3-5% of all cases of breast cancer. It is called “medullary” carcinoma because a tumour is a soft, fleshy mass that resembles a part of the brain called the medulla.

Medullary carcinoma is more common in women who have a BRCA1 mutation. Studies have shown that medullary carcinoma is also more common in Japan than in the United States.

Medullary carcinoma cells are usually high-grade in their appearance and low-grade in their behaviour. In other words, they look like aggressive, highly abnormal cancer cells, but they don’t act like them. Medullary carcinoma doesn’t grow quickly and usually doesn’t spread outside the breast to the lymph nodes. For this reason, it’s typically easier to treat than other types of breast cancer.
