Final answer:
Cancers can be asymptomatic, symptoms vary widely and depend on the cell type affected, and bleeding can be a symptom of cancer
Step-by-step explanation:
Some cancers, even advanced cancers, can be asymptomatic. This means that a person may have cancer without experiencing any symptoms. The symptoms of cancer vary widely. Symptoms can range from fatigue and weight loss to pain, coughing, and changes in bowel habits. The symptoms of cancer are dependent on the cell type affected. Different types of cancer cells may cause different symptoms. For example, lung cancer may cause a persistent cough and shortness of breath, while breast cancer may present with a lump in the breast.
Additionally, symptoms of cancer can include bleeding from ulcerated tumors. Ulcerated tumors may bleed, leading to symptoms like rectal bleeding in colorectal cancer or blood in the urine in bladder cancer. It is important to remember that not all cancers will present with symptoms, and some symptoms may be similar to other conditions. If concerned, it is best to consult a healthcare professional.
