Invasive lobular carcinoma is a type of breast cancer that begins in the milk-producing glands (lobules) of the breast.
Invasive cancer means the cancer cells have broken out of the lobule where they began and have the potential to spread to the lymph nodes and other areas of the body.
Invasive lobular carcinoma makes up a small portion of all breast cancers. The most common type of breast cancer begins in the breast ducts (invasive ductal carcinoma).
At its earliest stages, invasive lobular carcinoma may cause no signs and symptoms. As it grows larger, invasive lobular carcinoma may cause:
Invasive lobular carcinoma is less likely than other forms of breast cancer to cause a firm or distinct breast lump.
Make an appointment with your doctor if you have any signs or symptoms that worry you. Your doctor will perform an examination and determine whether you need a diagnostic breast X-ray (mammogram) or a breast ultrasound.
Ask your doctor when to begin screening tests for breast cancer to help detect cancer early and before you may have any signs or symptoms. Routine screening tests may include a physical exam and a mammogram.
Various organizations differ on their screening recommendations, but many suggest women with an average risk of breast cancer consider beginning mammograms in their 40s.
If you have a family history of breast cancer or other factors that increase your risk of breast cancer, your doctor may recommend beginning screening mammograms or other tests at an earlier age.
Each breast contains 15 to 20 lobes of glandular tissue, arranged like the petals of a daisy. The lobes are further divided into smaller lobules that produce milk for breast-feeding. Small tubes (ducts) conduct the milk to a reservoir that lies just beneath your nipple.
It’s not clear what causes invasive lobular carcinoma.
Doctors know that invasive lobular carcinoma begins when cells in one or more milk-producing glands of the breast develop mutations in their DNA. The mutations lead to the inability to control cell growth, which results in the cells dividing and growing rapidly. Depending on the aggressiveness of the cancer type, the cancer cells can spread to other parts of the body.
Lobular carcinoma cells tend to invade breast tissue by spreading out in a distinct way rather than forming a firm nodule. The affected area may have a different feel from the surrounding breast tissue, more like a thickening and fullness, but it’s unlikely to feel like a lump.
Factors that may increase your risk of invasive lobular carcinoma include:
Inherited genetic cancer syndromes. Women with a rare inherited condition called hereditary diffuse gastric cancer syndrome have an increased risk of both stomach (gastric) cancer and invasive lobular carcinoma.
Women with certain inherited genes may have an increased risk of breast and ovarian cancers.
To reduce your risk of breast cancer, consider trying to:
Discuss the benefits and risks of menopausal hormone therapy with your doctor. Combination hormone therapy may increase the risk of breast cancer.
Some women experience bothersome signs and symptoms during menopause and, for these women, the increased risk of breast cancer may be acceptable in order to relieve menopause signs and symptoms.
To reduce the risk of breast cancer, use the lowest dose of hormone therapy possible for the shortest amount of time.
Maintain a healthy weight. If your current weight is healthy, work to maintain that weight.
If you need to lose weight, ask your doctor about healthy weight-loss strategies. Reduce the number of calories you eat each day and slowly increase the amount of exercise. Aim to lose weight slowly — about 1 or 2 pounds a week.
If you have a family history of breast cancer or feel you may have an increased risk of breast cancer, discuss it with your health care provider. Preventive medications, surgery and more-frequent screening may be options for women with a high risk of breast cancer.

Diagnosed with breast cancer, Kristin Ferguson needed chemotherapy after a mastectomy. Uneasy about losing her hair, she was relieved to be offered a way to keep her long locks intact with cold cap therapy. It was during a March 2016 visit to the hair salon that Kristin Ferguson first heard about cold cap therapy. She […]
