At its earliest stages, invasive lobular carcinoma may cause no signs and symptoms. As it grows larger, invasive lobular carcinoma may cause:
- An area of thickening in part of the breast
- A new area of fullness or swelling in the breast
- A change in the texture or appearance of the skin over the breast, such as dimpling or thickening
- A newly inverted nipple
Invasive lobular carcinoma is less likely than other forms of breast cancer to cause a firm or distinct breast lump.
When to see a doctor
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 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 breast X-ray (mammogram).
Various organizations differ on their screening recommendations, but many suggest women with an average risk of breast cancer consider beginning yearly 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.
