1. Weight loss without exerting effort. Almost 50% of cancer patients lose weight. It's usually one of the first signs they notice.
2. Fatigue. Tell your doctor if you're constantly fatigued and resting doesn't help. Leukemia can exhaust you, while colon or stomach cancer might cause blood loss. Cancer-related weight loss might also make you tired.
3.Pain. Bone cancer is generally painful from the start. Some brain tumors generate persistent headaches that do not improve with treatment. Pain can also be a late indicator of cancer, so if you're not sure why it's happening or it doesn't go away, visit a doctor.
4. Changes in the appearance of your skin. To ensure that skin cancer isn't hiding, have your doctor examine any unusual or new moles, bumps, or marks on your body. Other types of malignancies can be detected by looking at your skin. It could be an indication of liver, ovarian, or kidney cancer or lymphoma if it's darker, looks yellow or red, itches, or sprouts more hair, or if you have an inexplicable rash.
5. Fever. Call your doctor if it's too high or lasts more than three days. Some blood malignancies, such as lymphoma, can cause a fever that lasts for days or weeks.
6. Sores that refuse to heal. Bleeding spots that refuse to go away are also indicators of skin cancer. Sores in the mouth might be the first sign of oral cancer. You're at a higher risk if you smoke, chew tobacco, or consume a lot of alcohol.
