Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
1. As there is the history of
lung cancer in family and pain in breast is for 1 year thus I have the following opinion [as I'm unable to examine you directly]:
i. Pain [mastalgia] could be due to fluctuating hormones after
menopause, or because of an infection,
abscess, cyst, oral contraceptives, antidepressants.
ii. As a rule of thumb: after the age of 35 years self-breast examination every month and if one notice any lump, discharge or skin change, it should be reported immediately.
iii. In best interest, it is wise to consult a gynecologist for a
Mammogram [to examine the breast for diagnosis and screening], since it could be
breast cancer that has spread to the lungs or lung cancer that has spread to the bone [back problems]. Thus simultaneously check with a chest specialist for lung
biopsy, computerized
tomography [CT], PET [positron emission tomography], bone scan, lung function test.
PS. Carcinoma of the breast if detected early is completely curable, particularly in postmenopausal women, and if it comes normal only thereafter lifestyle changes, alternative medicines and medications [HRT], can be discussed.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Munish Sood
