Transitional cell carcinoma of urinary bladder in a breast cancer survivor.

There is a propensity for the development of second malignancy in breast cancer patients either simultaneously with the first primary malignancy or after the control of the primary disease. The commonest sites to be involved with second malignancy in breast cancer patients are ovary, colon and endometrium. Other malignancies can also develop rarely either as a complication of treatment or de Novo. Here, a rare case is presented who developed transitional cell carcinoma of the urinary bladder 10 years after the treatment for breast cancer.
