Your symptoms are most suggestive of local trauma/bruise or muscle-rib pain, especially since pain occurs only on touch/pressure and there is a brownish mark. This is unlikely to be cancer. Mild size difference can be normal. Use warm compresses, avoid pressure on the area, and take a mild painkiller if needed. If pain or discoloration persists beyond 2–3 weeks, or if you feel a lump, consult a surgeon/gynecologist for examination and ultrasound.
