How To Detect Cancer Early On


Cancer is one of the most critical and threatening diseases in the world. Many people believe that cancer has no cure. However, if you detect cancer at the right time, it can be cured entirely. This article brings you the early signs and symptoms of cancer. 

What Are The Symptoms And Signs?

Symptoms and signs are signals of illness, injury, disease. These are the signals that tell you there’s some problem in our body. 

A sign is a kind of signal that someone else can see. For example, a doctor, maybe a loved one, other health care professionals, or a nurse. Abnormal lung sounds, fast breathing, and fever may be signs of pneumonia checked by a doctor using a stethoscope. 

A symptom is a type of signal that is noticed or felt by you or the person who is facing the problem. Others cannot see a sign so easily. Some examples are aching, weakness, and feeling short of breath are possible symptoms of pneumonia.

If you have one symptom or sign, it may not be sufficient to know the primary cause of the problem. A child having rashes can indicate many things at the same time. It can be measles, poison ivy, food allergy, or a skin infection. But if your kid has chilled, high fever, sore throat, and achiness with rashes, you or the doctor can better understand the illness. Sometimes, the symptoms and signs of a patient do not give any hints to the doctor. In that case, the patient has to get blood tests, x-rays, medical tests, and biopsy to know the illness. 

Symptoms And Signs Of Cancer

We should know that cancer is a group of diseases. It can cause many kinds of symptoms and signs in the body. These symptoms depend on how giant the tumor is, where it is located, and how much it affects the tissues and organs. If cancer has spread to many parts, there can be many symptoms and signs. 

When the size of cancer increases, it begins to reach blood vessels, nearby organs, and nerves in the human body. If the cancer is present in the brain, even a small size can cause significant symptoms. 

However, at times, cancer starts in such areas where it shows no symptoms and signs. It has to grow big to show symptoms. For example, cancer of the pancreas will not show any sign until it grows big and pushes the organs nearby. Belly or back pain are common signs of this type of cancer. Some kinds of cancers grow near the bile duct and hinder the bile flow in our body. The skin starts becoming yellow, and the eyes become pale. It causes jaundice. Such signs only come in the advanced stage of pancreatic cancer. It means that cancer has grown and expanded. 

Unexplained Weight Loss

When a person begins to lose weight, even when he’s eating well and has no other issues, it might be a sign of cancer. In the esophagus, lungs, pancreas, and stomach cancers, one loses weight without any explanation. 


If a person begins to get tired even after rest, it can be a symptom of delayed cancer. In leukemia, fatigue comes early. One should take it as an essential sign and get the checkup done. Some stomach or colon cancers may also result in blood loss. It is a reason why cancer causes fatigue. 


Fever is a sign of cancer, but it starts when cancer has already spread to some portions other than where it began. Many people who have cancer get feverish at one time. It happens because the treatment of cancer affects our immune system. Fever makes it difficult for the human body to fight infections. In lymphoma and leukemia (blood cancers), fever is an early sign. 

Skin changes

With skin cancers, few other kinds of cancers can also show changes in our skin’s behavior. These symptoms and signs are:

  • Jaundice or Yellowish eyes and skin
  • hyperpigmentation or Darker looking skin 
  • Erythema or Reddened skin 
  • Pruritus or Itching 
  • Excessive growth of hair on the body


With testicular cancer and bone cancer, pain is an early sign of a problem. If you have a headache that isn’t going away after medicines, rest, eye checkup, and better treatment, it may be a symptom of a brain tumor. If one has Back pain, it might be a cancer symptom for the ovary, rectum, and colon. If you face discomfort due to cancer, it means cancer has already spread through. 

Pelvic Pain Or Abnormal Periods

If you have never had abnormal periods or pelvic problems and suddenly start, they might be a symptom. Persistent pain can be a cause of ovarian or cervical cancer. 

Changed Bathroom Habits

When your bathroom changes habits, it can be a cause of prostate, colon, bladder, or other cancers. Some warning signs are diarrhea or persistent constipation, red or black blood in stool; tarry stools; blood in urine, and frequent urination. 


While we may feel bloated sometime or the other, if it lasts for more than two weeks, it may be a sign of gastrointestinal or ovarian cancer. If you find any sign of long-lasting bloating, you should consult your doctor and get the checkup done. 

Breast Changes


These may include dimpling, a new lump, and changes around the nipples, discoloring, or strange discharge that hasn’t been noticed by you before. Breast cancers generally occur in women. However, men can develop it, as well. 

Oral Changes

These occur in people who smoke and consume tobacco. Oral changes like swelling in the mouth and pain are signs of oral cancers. Sores and lesions in your mouth must not go unnoticed.

Difficulty In Swallowing Food

If a person finds it hard to swell food for more than two weeks, they should see their doctor. Swallowing problems for a long time can be a symptom of stomach, lung, or throat cancer.

Although symptoms like fatigue and fever are often due to other minor reasons, it is always better to avoid the risk and seek help.
