6. BLEEDING

Bleeding is always a red flag and it signals that something is wrong or has been violated. But in association with cancer cases, it is usually related to lung, colon, rectal, cervical, endometrial, bladder, kidney, or breast cancers. It is one of the common problems of cancer patients that can be traced to local tumor invasion or tumor angiogenesis and is essentially the effect of cancer or the treatment.

Also, some patients can develop some degree of acute catastrophic bleeding, major episodic one, or low-volume oozing. In each case, it can appear as bruising, petechiae, epistaxis, hemoptysis, hematemesis, hematochezia, melena, hematuria, or vaginal bleeding.
