Background: Clinically,Locally advanced breast cancer is a challenge because majority of patients develop distant metastases even after receiving the recommended therapy. Advanced breast cancer locally defined as large tumours size (> 5 cm), involvement of the overlying skin, invasion of chest wall, palpable axillary nodal (matted or fixed), or internal mammary and infraclavicular, or supraclavicular nodal involvement, as well as inflammatory carcinomas. The prognosis for locally advanced breast cancers depends on tumour size, the extent of lymph node involvement, and histological classification.
Objective: This study aimed to discuss locally advanced mucin-producing breast cancer.
Case report: Oncology Department referred a 27-year-old lady with a right breast lump that had been enlarging for more than two years to the surgical clinic because she was apprehensive about undergoing diagnostic tests. Physical examination revealed that she had no palpable mass in her right axilla and that her right nipple was entirely distorted and not even identifiable within the lump. The tumour totally replaced the right breast and was around 15 cm long.
Conclusion: Treatment coordination between medical oncology, surgical oncology, and plastic surgery is crucial in all instances of advanced breast cancer locally. Uncommon in young individuals, locally advanced breast mucinous carcinoma is a rare kind of cancer breast.
