Hello,
Yes, any cancer can be hereditary, but it is even more so if it happens at a younger age especially before 40.
So if you can find out whether the affected family members were diagnosed before or after 40, that can provide vital clues.
Now coming to your symptoms, they can result from various causes, however, they require detailed evaluation.
If I were your treating doctor, I would like to examine you in detail, rule out possible and common infections, and do some blood tests, to begin with.
Depending upon the findings will take things further. Yes kindly show to a physician, because your symptoms are worth a trip to the docs.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Jatin Bhatia,
Radiation Oncologist
