Unexplained Bleeding

The patient may have abnormal bleeding in a variety of places depending on the organ where the malignancy is located. Vomiting blood, coughing up blood, blood in the urine, and bloody feces are just a few examples of bleeding symptoms. Abnormal vaginal bleeding can be caused by vaginal and cervical malignancies during periods, after intercourse, or after menopause. Furthermore, continuous bleeding under the skin (bruising) might be a symptom of cancer, as it can disrupt blood clotting - hemostasis.

The symptoms caused by the disease may emerge single or in combination, or have additional symptoms, depending on the location of the malignancy, the level of invasion to nearby organs, blood vessels, nerves, or spreading throughout the entire body. For example, lung cancer with mediastinal lymph node metastasis can cause a persistent dry cough, as well as weight loss and fatigue; stomach cancer in its early stages can cause digestive problems (which can be easily confused with other benign stomach and esophageal diseases such as ulcers, reflux...), as well as tiredness and weight loss.
