Final answer:
Symptoms of breast disease not shown on a mammogram include nipple discharge. Mammography is effective but has limitations, especially in younger women with denser breasts; MRI can supplement detection. Monthly self-exams are crucial for early detection of subtle changes.
Step-by-step explanation:
The symptoms of possible breast disease that may not be demonstrated on a mammogram include nipple discharge, which is a concern because mammograms are designed to detect changes in breast density rather than discharge or fluid. Skin thickening, circumscribed tumors, and stellate lesions, however, are structural changes that can be seen on a mammogram. While mammograms are vital in the early detection of breast cancers, they are not infallible. X-rays have limitations due to the similar absorption rates in different types of soft tissue, which is particularly challenging in younger women with denser breast tissue. The use of MRI (Magnetic Resonance Imaging) as a supplementary tool has helped improve the detection rate and reduce false positives.
Other symptoms like lumps in the breast or elsewhere, chronic indigestion or difficulty swallowing, obvious changes in a wart or mole, and persistent coughing or hoarseness are also important to be aware of as they can be early warning signs of cancer. It's crucial for a woman to perform a monthly breast self-exam to notice any subtle changes that might indicate breast cancer.
