The main clinical manifestation of breast inflammation is that the patient feels swelling and pain in the breast, and the patient’s breast becomes locally red, swollen, and feverish. In clinical practice, the local manifestations of patients may vary individually, for example, in patients treated with antibacterial drugs, the local symptoms may be masked, and the manifestation of cellulitis is usually present at first, and an abscess may be formed after a few days. The abscess may ulcerate outward, and deep abscesses may even penetrate into the loose tissue between the breast and pectoral muscle, forming a deep breast abscess. If a breast abscess develops, the patient’s systemic symptoms will further worsen, and timely incision and drainage is required to cure the patient’s condition.
