16 Potential Warning Signs of Cancer that People Too Often Ignore

Doctors always recommend paying special attention to warning signs that might indicate undiagnosed cancer. Early detection of this disease increases the chances of successful treatment. Although the warning signs and symptoms in this post might not necessarily mean cancer in all cases, you shouldn’t neglect them. Instead, analyze the signs and symptoms you do experience, and then visit your doctor.

There are even more than 200 types of cancer, but in this article we will mention the most common ones: leukemia, melanoma, colorectal, endometrial and pancreatic cancer, lung, breast, prostate, bladder, ovarian, and kidney (renal) cancer. Most of these cancer types are difficult to be successfully treated, especially when it comes to lung cancer, and the main reason is the late detection.

Here are some of the most common signs and symptoms of cancer. Make sure to consult your doctor immediately if you experience some of them.

  1. Unexplained Weight Loss

If you notice that you are losing weight for no obvious reason, it could mean that you have lung or breast cancer. When the cancer reaches the liver, it disrupts its function to remove toxins and regulate appetite, thus causing weight loss. However, this can also be a sign of colon cancer.

According to the statistics, 40% of all cancer patients report that they experience sudden weight loss at the time of diagnosis, and up to 80% of advanced cancer cases are experiencing cachexia (general ‘wasting’) and unexplained weight loss.

  1. Fatigue and Weakness

If you are experiencing constant fatigue and weakness, and you still rest enough and get more sleep, consult your doctor immediately since it can be a symptom of many cancers.

  1. Frequent Fevers or Infections

As we all know, fever is a sign that your body fights an infection, but if it’s persistent, it can be a sign of  lymphoma. Moreover, the cancer of the blood cells, leukemia can cause signs like fatigue, aches, fever, frequent infections and many other flu-related symptoms.

Moreover, if you notice that your voice is hoarse for more than 6 weeks, also consult your doctor immediately, because the cases with horse voice usually indicate laryngeal cancer, lung, thyroid and esophageal cancer.

  1. Bloating

Ovarian cancer causes frequent bloating for no apparent reason and over a longer period of time. In addition, if you also experience swelling in the abdomen, feeling fullness and pelvic pain, you should definitely consult your health care provider and check whether you have ovarian cancer. Similarly, bloating or pain in the stomach after eating might indicate a stomach cancer.

  1. Chronic Heartburn

As we all know, acid reflux causes heartburn, but on the other hand, if it’s persistent, it might be related to esophageal cancer or Barrett’s esophagus. According to one study published in the journal Clinical Gastroenterology and Hepatology chronic heartburn can cause inflammation of the tissue lining in the esophagus that in turn raises the risk of esophageal cancer.

Burning sensation or pain when swallowing are the other two symptoms of this type of cancer.

  1. Jaundice

  • new spots, growths, or sores on the skin that don’t heal
  • changes in color, symmetry, diameter, or border of your existing mole
  1. Nail Changes

Bleeding from the gastrointestinal tract is a warning sign of colorectal cancer.

Warning signs of leukemia are excessive and persistent bruising and bleeding. Vomiting or coughing blood is an indicator of lung and esophageal cancer, as well as of stomach cancer. However, abnormal bleeding is not always a symptom of some type of cancer, it can also indicate other serious conditions and diseases.
