No: There is no scientific evidence that dietary soy food (milk, tofu, ect...) is linked to the development of breast cancer in women or men. And it does not cause lumps in men's breasts. If a man has a lump in his breast, he should immediately go see his doctor for an assessment. Breast cancer does develop in men, albeit much less common than in women.
