It's not worth taking the risk is it? Herbs sound innocent because they are natural but some herbs can have a disastrous effect on the body and if you are already predisposed to cancer, it is one hell of a gamble to take. Remember that if they actually work, it is because you are taking a dose high enough to alter the balance of hormones in your body. Some cancers are sensitive to estrogen and this would 'feed' the tumour which is why pregnancy can accelerate certain aggressive cancers (pregnancy incidentally causes bigger breasts due to the shift in hormones).
Why don't you try massage or a suction method instead? Suction has been tested by doctors (most herbs have not) and is not a carcinogen.
Remember that your health is the most important thing.
