Have Parkinsons Disease. Noticed Large Canker Sore Under Tongue. Could I Have Malignancy In Body?
Thanks for the query
After going through the description, I feel the numbness is very unlikely to be secondary to malignancy.
I do agree with the fact that recurrent canker sore could behave as a premalignant condition. But in your case, the ulcer has already healed and it is only the numbness which is prevailing. Hence the numbness could be due to peripheral neuritis which is an age related changes in the nerves.
The skin over the chin is supplied by the branches of the trigeminal nerve and the ulcer was present in the floor of the mouth, which is innervated by branches of the lingual nerve, the mylohyoid nerve. So in this case, if at all you were to be having any malignancy it could have caused numbness in the floor of the mouth rather than the anterior part of the chin. Hence, there is no relation between the numbness and the malignancy.
Secondly, the generalized weakness could be related to hormonal changes in the post menopausal period, reduction in hemoglobin, etc. which requires a thorough evaluation. My advice to you is to consult your doctor for a complete check-up and further management.
Hope I have answered your query; I will be available for the follow-up queries.
