Special considerations for radiotherapy after breast conserving therapy for invasive breast cancer

Breast conserving therapy including radiotherapy contraindications:

Absolute:

* radiotherapy during pregnancy

Diffuse calcification of suspicious or malignant appearance

* extensive lesions can not be achieved by a single incision with local resection to achieve a negative cutting edge with satisfactory cosmetic results

* borderline pathology diffuse positive

Relative:

* previous chest wall or breast radiotherapy; it is necessary to know the dose of the prescription and the target area.

* the activity of connective tissue disease involving the skin (especially scleroderma and SLE)

* tumor > 5cm (grade 2B)

* pathological positive margin

A woman with a known or suspected predisposition to breast cancer:

In breast conserving therapy may have ipsilateral breast recurrence or increased risk of contralateral breast cancer

In order to reduce the risk, can consider bilateral prophylactic mastectomy

(see genetic / familial risk assessment for breast and ovarian NCCN guidelines).
