  • A hard time swallowing
  • Discomfort after eating
  • Changes in bowel or bladder habits

How does smoking cause cancer?

  • – Cigarettes cause cancer because they have harmful chemicals.
  • – When you smoke, these chemicals enter your body and damage your cells.
  • – The main harmful chemicals in cigarettes include tar, nicotine, and carbon monoxide.
  • – Smoking damages the DNA in cells, which controls how cells grow and behave.
  • – Damaged DNA makes cells behave abnormally, and over time, this can lead to cancer.
  • – Nicotine is addictive and keeps people smoking.
  • – Cigarette smoke has about 7,000 chemicals, many from burning tobacco leaves.
  • – Over 70 of these chemicals are known to cause cancer.

– Smoking harms almost every organ in the body, leading to various diseases and reducing overall health

 Types of cancers caused by smoking ?

The connection between smoking and cancer is obvious. Smoking causes different kinds of cancer, including lung cancer and bowel cancer, which are very common. There is also increasing evidence that smoking may cause other cancers, such as breast cancer, but we need more reliable research to confirm this.

Types of CancerArea Affected
Lung cancerLungs
Nose and Sinuses cancerNose and Sinuses
Bowel cancerBowel
Pharynx cancerUpper Throat
Larynx cancerVoice Box
Oesophagus cancerFood Pipe
Some types of leukemia cancerBlood and Bone Marrow
Pancreas cancerPancreas

Smokeless tobacco, such as chewing tobacco also causes cancer including cancers of the:

  • Oesophagus
  • Mouth and throat
  • Pancreas

 How Does Smoking Increase Your Risk of Lung Cancer?

When you inhale tobacco smoke, thousands of chemicals enter your lungs. Many of these chemicals can damage the DNA in your lung cells.

Your body tries to repair this damage, but smoking can cause more harm than your body can fix over time. This ongoing damage may eventually lead to the formation of cancer cells.

Inhaling tobacco smoke also damages the tiny air sacs in your lungs called alveoli. These air sacs are crucial for gas exchange, moving oxygen into your blood and expelling carbon dioxide when you breathe out.

Over time, damage to the alveoli can lead to chronic obstructive pulmonary disease (COPD).

Different Ways to Treat Mouth Cancer

There are several ways to treat mouth cancer:

1. Surgery

   – Doctors can remove the cancerous tumour and some surrounding healthy tissue to ensure all cancer cells are gone. In advanced cases, parts of the mouth, throat, or lymph nodes may also need to be removed.

2. Radiation Therapy

   – This uses high-energy beams, like X-rays, to kill cancer cells. It’s often used after surgery to kill any remaining cancer cells. Sometimes, it is used alone for early-stage cancers.

3. Chemotherapy

   – This treatment uses drugs to kill cancer cells. It can be used alone or with radiation therapy. Chemotherapy is especially useful for advanced cancer.

4. Targeted Drug Therapy

   – These drugs target specific aspects of cancer cells that help them grow. For example, Cetuximab is a targeted drug that blocks a protein that helps cancer cells grow. This therapy can be used alone or with chemotherapy and radiation.

5. Immunotherapy

   – This treatment helps your immune system fight cancer. It is usually used for advanced mouth cancer that doesn’t respond to other treatments. Immunotherapy works by blocking proteins that hide cancer cells from the immune system.

Each treatment method has different side effects. Doctors will choose the best option based on the stage and type of cancer, as well as the patient’s overall health.

Early symptoms include persistent sores, lumps, and difficulty swallowing or speaking. Mouth cancer is diagnosed through physical examinations and biopsies. Treatment options include surgery, radiation therapy, chemotherapy, targeted drug therapy, and immunotherapy.
