Advice about Breast Cancer

[Rob-uk]

Hi,

My mother-in-law has just been diagnosed with breast cancer, she's 57 and has had the lump for over a year and never said a word to anyone, which is extremely anoying!!

Anyway, she was put on Tamoxifen for a week and then taken off them because the particular type of cancer that she has is supposedly very rare (and probably doesn't respond to it)

She is extremely anxious and stressed with high blood pressure and has Vitamin B12 deficiency. Her eyesight has deteriorated so much that she can't really do much. She's had her eyes checked out and they are perfectly okay. She also seems shaky and not quite with it.

Can anyone shed any light on what's happening? Is it the cancer, high blood pressure, B12 deficiency or stress that's causing her eyesight problems?

Grateful for any advice

Rob
