Understanding the symptoms of all types of cancer, including the earliest signs, plays a crucial role in improving survival and treatment outcomes.
According to the World Health Organization (WHO), in 2022 alone, there were an estimated 20 million new cancer cases and 9.7 million cancer-related deaths. Shockingly, 1 in 5 people will develop cancer in their lifetime.

How Cancer Develops and Why Early Symptoms Matter

Cancer is not just one disease—it is a collection of over 100 diseases where cells grow uncontrollably, sometimes forming tumors, and may invade other parts of the body. Recognizing cancer common symptoms early can be life-saving.

In some cases, such as leukemia, visible tumors do not form. In others, like breast or colon cancer, physical symptoms may become obvious only when the disease has progressed. This is why being aware of the 7 signs of cancer or even subtle symptoms can help ensure early medical attention.

Some patients ask, “What are the 7 symptoms of cancer?” or “How to know cancer symptoms before it’s too late?” The answer lies in paying attention to what your body is telling you and seeking screening when needed.

Common Types of Cancer

Some of the most popular cancer types affecting both men and women globally include:

• Bladder Cancer
  
• Breast Cancer
  
• Colon and Rectal Cancer
  
• Lung Cancer
  
• Prostate Cancer
  
• Thyroid Cancer
  
• Liver Cancer

• Pancreatic Cancer
  
• Endometrial Cancer
  
• Kidney Cancer
  
  

Classification by Cell Type

Cancers are grouped into main categories depending on the type of cell where they begin:

• Carcinomas – Affect skin or lining of organs (e.g. breast, colon, lung cancer)
  
• Sarcomas – Originate in bone, fat, muscle, or cartilage
  
• Leukaemia – Starts in blood-forming tissue like bone marrow
  
• Lymphomas – Begins in immune system tissues
  
• Melanomas – Arise from skin pigment-producing cells
  
• Central Nervous System Cancers – Develop in brain and spinal cord
  

7 Common Symptoms of Cancer

Here are the 7 cardinal signs of cancer you should never ignore:

1. Sudden Weight Loss
   Rapid and unexplained weight loss can be an early warning sign, especially for pancreatic, stomach, or lung cancer.
   

2. Lumps or Swelling
    New or unusual lumps—particularly in the breast, neck, or groin—should be evaluated immediately.
   

3. Persistent Cough or Hoarseness
   If you’ve had a cough that won’t go away for weeks, or your voice changes, it may point to lung or throat cancer.
   

4. Chronic Pain
    Pain that doesn’t improve or has no clear cause—especially in the back, bones, or joints—could be related to cancer.
   

5. Changes in Bowel or Bladder Habits
   Blood in the stool or urine, prolonged constipation, or frequent urination may be signs of colon or bladder cancer.
   

6. Fatigue
   Constant exhaustion, especially if paired with other symptoms, is a common yet often overlooked general cancer symptom.
   

7. Unusual Bleeding or Discharge
   Vaginal bleeding outside of regular cycles, bleeding gums, or nipple discharge should be discussed with a doctor immediately.
   

Early Detection and Prevention Tips

Self-Examinations

Get into the habit of performing monthly breast and testicular self-checks to detect any lumps early.

Regular Screenings

Undergo recommended health checks such as:

• Mammograms (breast cancer)
  
• Pap smears (cervical cancer)
  
• Colonoscopies (colon cancer)
  
• Skin checks (melanoma)
  

These methods are crucial for spotting types of cancer and their symptoms before they advance.

Know Your Family History

If a close relative has had cancer, your risk may be higher. Early and frequent screenings are vital.

Lifestyle Choices

Adopt a healthy lifestyle: balanced diet, regular exercise, and avoiding tobacco and alcohol all reduce cancer risks significantly.

Alternative Support: Cannabinoids and Cancer Care

Some studies are exploring cannabinoids for cancer relief, particularly in managing chemotherapy-induced nausea, appetite loss, and chronic pain. While not a cure, this alternative approach is being considered in integrative cancer treatment programs.
