From a global stand point, cancer is one of the leading causes of premature death. 

Sometimes cancer can develop without warning signs, but in most cases, the symptoms are well noticed. The earlier the signs are detected, the better the chances of survival.

Most Common Cancers

According to the National Cancer Institute, the most prevalent cancers excluding nonmelanoma( skin cancers) are:

  • Colon and rectal cancer
  • Bladder cancer
  • Endometrial cancer
  • Breast cancer
  • Leukemia
  • Kidney cancer
  • Thyroid cancer
  • Melanoma
  • Liver cancer
  • Prostate cancer
  • Pancreatic cancer
  • Lung cancer
  • Non-Hodgkin’s lymphoma 

Skin cancer is the most common cancer with breast and lung cancer taking up the second and third most prevalent cancers as they are several persons diagnosed with these increase yearly. 

The précised symptoms of various forms of cancers differ. Some cancers, such as pancreatic cancers, do not show signs immediately. Still, there are some significant signs you can look out for. These include:

Weight Loss

Weight loss might be your body’s way of responding to cancer development. This is because cancer cells mainly attack your body cells. 

Unexplained weight loss can be a result of other health conditions such as hyperthyroidism. The difference here is that weight loss caused by cancer is sudden. Cancer of the esophagus, pancreases, lungs, and stomach are the most common cancers with this symptom.


Generally, fever is the body’s way of responding to inflammation, infection, or sickness. People with cancer will often have a fever as a symptom. Fever mostly indicates that cancer has migrated to an advanced stage or has spread, but on rare occasions like in blood cancer (leukemia or lymphoma), it serves as an early sign.

Blood Loss

Some cancers may cause unusual bleeding. for example, prostate and bladder cancer might cause bloody urine, and there might be blood in stool in cases of rectal and colon cancers. on the other hand, blood loss may be undetectable in stomach cancer because it may be internal. 

Pain And Tiredness

Baffling or Unexplainable fatigue is one of the most common symptoms of cancer. Prolonged tiredness, even after enough rest, could be a symptom of underlying health problems, cancer inclusive. 

Tiredness is most outstanding in leukemia cases.

Back pain may be experienced in cancers of the ovaries, rectum, colon, or prostate.

Persistent Cough

Cough is the body’s natural way of getting rid of unwanted substances. Flu, allergies, colds, or even low humidity can lead to a cough. 

However, when it comes to lung cancer, the cough can persist despite remedies. Here, the cough is frequent and can also cause hoarseness. With the progression of lungs cancer may come bloody sputum.

Skin Changes

Skin changes are mostly linked to skin cancer.

Specific skin changes may be an indication of several forms of cancer, for example, white spots in the mouth indicate oral cancer in the same vein, bumps, and lumps underneath the skin will show tumors such as in breast cancer. Other changes to the skin that can be an indication of skin cancer include redness, jaundice, or yellow eyes and skin, hyperpigmentation or dark spots, and decreased hair growth.

Changes In Digestion

Difficulty in swallowing, pain after eating, and changes in appetite could be an early indication of cancer. 

Difficulty swallowing will likely be an indication of cancers of the head and neck or, most likely, the esophagus. Also, the early stage of cancer of the stomach may not have many symptoms, but it can cause symptoms like bloating, indigestion, vomiting, and nausea.

Note that these symptoms are not only peculiar to gastrointestinal tract cancers. They can also be seen in ovarian or brain cancer. 

Night Sweats

Night sweats naturally cause you to get drenched in sweat. This can occur in many cancer cases. 

Nonetheless, night sweats can also be associated with earlier stages of several cancers, ranging from liver cancer to lymphoma and leukemia.

Cancers With No Warning Signs

Certain cancers are asymptomatic. Examples of these are the kidney, pancreatic, and certain forms of lung cancer. 

Some cases of lung cancer may not show a regular symptom, which is a persistent cough. Certain types/ forms will only cause increased blood calcium levels, and this can only be detected in laboratory test results.

Furthermore, Pancreatic cancer may not be asymptomatic until it gets to the advanced stage. Periodic pancreatic swelling, as well as family history, will increase your risk, and it is advisable to report to a health care provider who will recommend regular cancer screening.


The key to thriving against cancer is to take responsibility for your health. Make annual or regular checkups a habit and do all screening prescribed by your doctor, especially if you have a family line of cancer.
