UNDERSTANDING LUNG CANCER

Lung cancer usually begins in the bronchi and the alveoli. These are the target areas because when we breathe in, air enters through our nose or mouth. Then, it travels through the windpipe (trachea), into the bronchi and bronchioles. The oxygen we breathe in then moves into the alveoli, where it’s exchanged into the carbon dioxide we breathe out. This is the reason behind the common association between lung cancers and active smoking. Research by the American Cancer Society shows 87% of lung cancers are caused by smoking.

CAN FORMER SMOKERS STILL BE AT RISK?

Absolutely. While the odds are lower, the risk is elevated for those with a significant smoking history, measured in pack-years. However, lung cancer can still touch the lives of individuals who’ve chosen to quit. Factors like second-hand smoke exposure, outdoor air pollution, and occupational contact with substances like asbestos and uranium can also contribute.

TYPES OF LUNG CANCER

  • Small Cell Lung Cancer (SCLC): This variant, accounting for less than 15% of cases, primarily afflicts heavy smokers. Factors like workplace exposure to certain elements and radiation from diagnostic imaging contribute to its occurrence.
  • Non-Small Cell Lung Cancer (NSCLC): Categorized by stages, NSCLC provides insights into the extent of cancer spread. Its common subtypes—Adenocarcinoma, Large Cell Carcinoma, and Squamous Cell Carcinoma—are each marked by distinctive characteristics. Smoking remains a significant risk factor, causing 80-90% of these cases.

EARLY SIGNALS OF LUNG CANCER

Identifying early symptoms is the cornerstone of timely intervention. While some can only be unearthed through medical imaging, others make their presence palpable.

  • Bone Pain: Unlike muscle pain, bone pain restricts movement. Often felt in the neck, shoulders, and arms, it warrants attention.
  • Chest Pain: Radiating through the shoulders and back can be associated with various conditions. A professional diagnosis is advised.
  • Stubborn Cough: A persistent cough lasting over a month, especially with distinct sound qualities, could be indicative.
  • Shortness of Breath: Tumors can obstruct airways or prompt excess mucus production, leading to breathlessness.
  • Weight Loss: Unexplained weight loss, particularly up to 10 pounds, is a common precursor. Tumors consume substantial energy, affecting body weight.

Delaying early screening causes the tumour to grow and spread to other body organs. (Only 16% of lung cancer cases are detected during the early stages.)

ADVANCED SYMPTOMS OF LUNG CANCER

As symptoms evolve, so does the cancer’s progression. More advanced signs of lung cancer include:

  • Coughing Up Blood: A significant sign of advancement, it demands immediate attention.
  • Loss of Appetite: Consistent coughing can impede swallowing, leading to a diminished appetite.
  • Wheezing: Indicative of congested lungs, it makes breathing more challenging.
  • Blood Clots: Associated with Small Cell Lung Cancer, they can be life-threatening, if not promptly addressed.

Seeking Swift Intervention

SEEK MEDICAL ADVICE EARLY

It’s crucial to debunk the misconception that lung cancer is invariably fatal. In reality, early-stage cancer is eminently treatable, with cure rates reaching 80% to 90%. If you’re regularly exposed to risk factors or possess a family history, seeking professional advice is paramount.
