crimsongull20 said:My dad dealt with night sweats, weakness, weight loss, swollen lymph nodes, and an enlarged spleen. For nearly a year, his friend kept telling him it was just stress, and he ended up getting sent home from the ER three separate times without anyone giving him any actual follow-up advice. He was eventually diagnosed with late-stage Non-Hodgkin lymphoma and lived for only 8 months after that.
The primary carcinoma was found in a groin lymph node. Thirteen years prior, because of a misdiagnosis, he had an X-ray where the technician forgot to use a lead shield, and they told him it wouldn't be wise to try for kids for a few years. It’s driving me crazy—what are the odds that he was irradiated enough back then to trigger a disease that started right in his groin?
Wait, did you mention before that your dad already had some kind of cancer? Remind me if you wrote that?
By the way,
carcinoma isn't the same thing as lymphoma. They come from entirely different cell types. Carcinomas originate in epithelial cells, whereas lymphomas stem from cells within the immune system. In that sense, the differences are massive; they are treated differently, they progress differently, and they have different prognoses. It’s unlikely for a primary carcinoma to show up in a lymph node; usually, that’s just a metastasis from a primary tumor located somewhere else.
Beyond lymphomas and carcinomas, you also have sarcomas which come from connective tissue, leukemias from blood-forming cells, melanomas from melanocytes, and gliomas from brain cells.
So, "cancer" isn't just one thing, even though people here tend to use the word as a catch-all term for everything because it's such a heavy, taboo subject that everyone avoids talking about directly.
Regarding radiation: yes, any part of the body that has been irradiated carries a risk of developing a new malignancy over several years as a consequence of that exposure. That’s why modern radiation equipment is becoming incredibly precise, designed to target only the diseased cells.
