i have a non tender left sub mandibular lymph mode swelling can it be cancerous?
hi dr. and welcome to questiondoctors. com it is rarely developing cancer this way. even if it is sudden onset. it would be due to an inflammation or infection that is not known yet or further symptomless. you should start by using a strong antibiotic like augmentin for at least 5 days…if the node did not subside then you should go for us and later biopsy if only needed… speedy recovery wishes.
