Chapter 1 - Diagnosis and Staging of Breast Cancer and Multidisciplinary Team Working
Over 90% of breast cancers (BCs) are local or regional when first detected. At least 60% of patients present with a breast lump, which may or may not be painful, fixed or demarcated from the surrounding tissue.
BC may cause skin or nipple retraction, discharge from the nipple, and/or changes in breast size or shape. Skin rash, ulceration, erythema and eczema of the nipple–areola complex may also occur.
A lump in the axilla or the supraclavicular fossa, skeletal or abdominal pain, cough, breathlessness or neurological signs or symptoms are suggestive of metastatic cancer.
Inflammatory carcinoma is characterised by erythema and oedema of the breast. It usually encompasses the entire breast or at least one third of the skin. The breast skin may resemble “orange peel”. A large diffuse mass is often present in the breast.
It is usually caused by poorly differentiated ductal cancer. Cancer cells obstruct the dermal lymphatic vessels and cause the skin oedema. A skin biopsy can give the diagnosis, as tumour emboli are found in the dermal lymphatic vessels, but a negative skin biopsy does not exclude the diagnosis.
Breast infection-related skin redness and oedema is often associated with fever and tenderness, which is not typical of inflammatory BC. In addition, some large-breasted women have mild erythema of the lower part of the breast. This is of no concern and disappears when lying down.
Paget’s disease is an eczema-like in situ cancer that involves the areola, the nipple or both.
Paget’s disease is associated with invasive or
A skin biopsy and breast imaging (mammography and breast ultrasound examination) should always be performed when a patient has persistent eczema in the nipple or the areola.
