Understand What Is Cancer? Its Signs, Symptoms,Types & Causes

Cancer is a complex and often misunderstood disease. It encompasses a group of diseases characterized by uncontrolled cell growth and spread to other parts of the body. Dr Gopal Sharma mentions that Recognizing the signs and symptoms early can be crucial for effective treatment and management.

What Is Cancer?

Cancer occurs when cells in the body begin to grow uncontrollably. These cells can form a mass called a tumour, which can be benign (non-cancerous) or malignant (cancerous). Malignant tumours can invade nearby tissues and spread to other parts of the body through the bloodstream and lymphatic system, a process known as metastasis.

Signs and Symptoms of Cancer

Cancer symptoms and indicators differ based on the kind and location of the
disease. Some general symptoms include:

• Unexplained Weight Loss: Sudden and unexplained weight loss can be a
sign of cancer.
• Fever : Persistent fever can be an indicator of cancer, particularly blood
cancers like leukaemia.
• Fatigue: Extreme tiredness that doesn’t improve with rest can be a
symptom.
• Pain: Persistent pain, particularly in the bones or joints, can be a sign.
• Skin Changes: Changes in skin colour, sores that don’t heal, and changes in
moles can be warning signs.
• Unusual Bleeding or Discharge: Blood in the urine, stool, or phlegm can
be a symptom of cancer.
• Lumps or Thickening: New lumps or thickening in the breast, testicles, or
elsewhere should be checked by a doctor.

Types of Cancer

Cancer can affect almost any part of the body. Some common types include:

• Carcinomas: Cancers that begin in the skin or the tissues lining internal organs.
• Sarcomas: Cancers that begin in the bones, cartilage, fat, muscle, or other
  connective tissues.
• Leukaemia: Cancers that start in blood-forming tissue such as the bone marrow
  and cause large numbers of abnormal blood cells to be produced.
• Lymphomas: Cancers that originate in immune system cells.

Causes of Cancer

Cellular DNA alterations, or mutations, are the root cause of cancer. These
mutations can be inherited, or they can result from environmental exposures, such
as:

•  > Tobacco: Smoking is linked to various types of cancer, including lung,
  mouth, throat, bladder, kidney, and others.
• > Radiation: Both ionizing radiation, such as radon, and ultraviolet radiation
  from the sun can cause cancer.
• > Chemicals: Exposure to certain chemicals, such as asbestos, benzene, and
  certain dyes, can increase cancer risk.
• > Viruses and Infections: Certain viruses, such as human papillomavirus
  (HPV) and hepatitis B and C, can increase the risk of cancer.
•  > Lifestyle Factors: Poor diet, lack of physical activity, and excessive alcohol
  consumption can increase cancer risk.
