[21F] Experiencing persistent breast tenderness and lump with systemic symptoms

What might be happening

Based on the information you've provided, here are some possibilities:

• Fibrocystic Breast Changes: This condition is characterized by breast pain, cysts, and noncancerous breast lumps. It's most common in women of childbearing age, but can affect women of any age. The condition often becomes less problematic after menopause.

  • Treatment typically involves managing symptoms. Over-the-counter pain relievers and supportive bras can help. In severe cases, your doctor may suggest surgery to remove a particularly painful or large cyst.

• Breast Cancer: Given the size, location, and your description of the lump, as well as your other symptoms (night sweats, weight gain, fevers), this is a possibility that must be considered. Breast cancer can also cause skin changes and discomfort in the armpit area.

  • Treatment options for breast cancer include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy.

• Mastitis: This is an infection of the breast tissue that results in breast pain, swelling, warmth and redness. It can also cause flu-like symptoms such as fever and chills.

  • Treatment typically involves antibiotics. In some cases, an abscess might need to be drained.

Please note that these are possibilities based on the symptoms you've shared and are not a definitive diagnosis. It's important to consult with a healthcare provider for a proper evaluation.

What you can do

1. Schedule an appointment with a healthcare provider as soon as possible. They can perform a physical examination and possibly order imaging tests like a mammogram or ultrasound to better understand what's causing your symptoms.
2. In the meantime, over-the-counter pain relievers can help manage your pain. Wearing a supportive bra might also provide some relief.
3. Keep track of your symptoms. Note any changes in the size or feel of the lump, as well as any new symptoms.

What you should look out for

Seek immediate medical attention if:

• You notice a sudden increase in the size of the lump
• Your symptoms significantly worsen
• You develop new symptoms such as nipple discharge, severe pain, or a high fever.
