Cancer is the second most common cause of death. It's more curable when detected earlier. Although some cancers develop completely without symptoms, some do have signs you are likely to ignore.

1. Unexplained Weight Loss
Weight loss for no known reason, not through changes in diet or exercise is a common sign of cancers related to lung, stomach or pancreas.
2. Fever
Fever may be a sign of early cancer in the blood such as leukemia or lymphoma. Fever may also reveal colon and kidney cancer at an early stage.
3. Fatigue
Extreme fatigue that cannot get better with rest can be a symptom of several cancer types such as colon cancer, stomach cancer or leukemia.
4. Pain
Sometimes bone cancer or testicular cancer can cause pain. A headache that doesn't get better after a long-time treatment may be a symptom of a brain tumor. Back pain may be a sign of cancer in ovary or colon.
5. Skin Changes
Any freckle, mole or wart that changes color, shape, or size should be examined for skin cancer. Besides, darker looking skin, reddened skin, itching, yellowish eyes and skin may also be linked to cancers.
6. Change in Bowel or Bladder Habits
Long-term diarrhea, constipation or a change in the size of the stool can be a symptom of rectal or colon cancer. Pain when passing or blood in urine can be related to bladder or prostate cancer.
7. Shortness of Breath
Cancer in or near the lungs may cause a blockage of the tubes that carry air. Breathlessness is also common with breast cancer tumors, ovarian or liver cancer.
8. Unusual Bleeding
Coughing up blood may be a sign of lung cancer. Blood in the stool or urine can forecast colon cancer or kidney or bladder cancer. A bloody discharge from the nipple can indicate breast cancer.
9. Lump
A lump that is usually hard, not painful, irregularly shaped or firmly attached deep in the soft tissue or under the skin is often caused by cancer.
10. Difficulty Swallowing
Mouth or throat cancers can make the swallowing difficult. It's also a common sign of various head and neck cancers such as esophageal, oropharyngeal cancer, thyroid and laryngeal cancers.
11. Nagging Cough
More than half of people who have a cough that just wouldn't go away are diagnosed with lung cancer. Excessive coughing is also common signs of laryngeal and thyroid cancer.
12. White Patches Inside the Mouth
White patches inside the mouth can be leukoplakia, which is pre-cancerous and can become mouth cancer if it's not treated early.
13. Heartburn
Heartburn that doesn't go away or gets worse could mean cancer of the throat, stomach, or ovaries. Excessive food, alcohol, or stress can cause serious heartburn.
14. Belly Pain and Depression
It rarely happens, but belly pain plus depression can be a sign of pancreatic cancer. But you don’t need to worry unless unless this disease runs deep in your family.
