[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should consult dermatologist and get done detailed clinical examination of skin lesion. As many cancers can involve cutaneous vessels and cause bleeding. Lung cancer is most common cause in this. Especially small cell carcinoma of lung. So chances of cutaneous vessels' involvement are more by tumor. So better to consult dermatologist and if needed biopsy of the lesion is also recommended.
