Inclusion Criteria

3. Tumour, measured on clinical examination, as greater than 2 cm in diameter
4. Postmenopausal
5. Adequate haematological, renal and liver function, defined as: platelets of greater than 100 x 10(9)/l, white blood cell count of greater than 3 x 10(9)/l, creatinine less than 110 mmol/l, aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) less than 1.25 x upper limit of normal

Exclusion Criteria
