Breast cancer can occur in young women (and men), although it becomes more common with increasing age. Whether the person is single or married does not make a difference.
Although I understand how concerned you must be about your daughter, we are unable to provide medical advice. This is a forum is a community of BC survivors and other interested contributors who for the most part are not identified as medical professionals. In any case, medical advice obtained over the Internet would be of limited value compared with that of the medical oncologist, who has actually examined your daughter and has access to all of her records.
The recommendation for a biopsy is certainly appropriate in ordere to obtain a definitive diagnosis of the breast lesion that has been detected. The surgeon will no doubt discuss with your daughter (and with you, if she requests that you attend the consultation with her), whether the lymph nodes would be checked by Sentinel node biopsy or by axillary dissection.
We certainly hope everything will be fine with your daughter, and would appreciate if
you would update us in regard to how things turn out.
Best wishes...
It is indeed very uncommon for a 19 year old woman to have breast cancer. It is to my knowledge, at least in the US, unheard off that a doctor, or father, or mother, of priest, or ANYONE for that matter believes a daughter's potentially malignant illness could be affected by her marital status. ( your implying that you can understand a married woman getting cancer, but surely not an unmarried, 'innocent' daughter?)
Please sir, get this out of your head right now, as you can surely not help your daughter with a suspicion on your mind like this; it is just not true, or related.
What your daughter is experiencing more likely than not is not cancer, but some form of inflammation that needs to be, and is being, investigated.
If you want to help your child, please listen to her and the doctors and be supportive?
