What should you know about hot breast lump?

Heat and tenderness often point toward inflammation, a blocked duct or an infection such as mastitis. A fluid collection may form if an infection is not settling. Hormonal changes and benign breast conditions can also cause a lump, while breast cancer can present with a lump or other breast change. A breast lump is a possible presentation of breast cancer, not proof that the lump is cancer. The texture, location, skin appearance and whether it changes over time help guide an examination.

Arrange a clinical assessment for a new hot lump rather than repeatedly pressing it. Note when it began, whether you are breastfeeding, and whether you have fever, nipple discharge or skin changes. Wear supportive clothing and use a cool compress for discomfort. Do not lance or squeeze the area. A clinician may examine the breast and decide whether imaging, antibiotics or drainage is appropriate.

Seek same-day medical advice for a rapidly enlarging lump, spreading redness, fever, chills, severe pain or pus. Get urgent help if you feel faint, confused or very unwell. Even without fever, arrange review when the lump is hard, fixed, associated with skin dimpling, nipple inversion or bloody discharge, or remains after inflammation improves.

Ask what the lump may represent, whether you need imaging or treatment, which changes should prompt urgent review, and when a follow-up examination is due.
