Prostate and Lung Cancer
Cancer that metastasizes (spreads) to the bones from other parts of the body such as breast, lung, kidney, prostate, hip-bone (pelvis), ribs and skull is called metastatic cancer. Cancerous cells break down and travel to nearby body organs/tissue from the very first place where originated.. These are named for the organ or tissue in which it began, for example, breast cancer that has spread to the lungs is called “metastatic breast cancer to the lungs”. The cells in metastatic cancer becomes uncontrollable making the treatment more difficult however treatment options for all types of metastatic cancer is available.
2) Prostate Cancer
Prostate cancer is a cancer that begins in the prostate — a small walnut-shaped gland in men that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is the most common type of cancer in men. It usually affects men over 50 and is rare in younger men. It varies from most other cancers in the body and does not show up for many years.
Most prostate cancers grow very slowly. But in a small proportion of men, prostate cancer can grow more quickly and in some cases may spread to other parts of the body, particularly the bones.
Early (localised) Prostate Cancer
Early cancer of the prostate gland (early prostate cancer) is when the cancer is only in the prostate and has not spread into the surrounding tissues or to other parts of the body.
Men with early prostate cancer may not have any symptoms, as these only occur when the cancer is large enough to put pressure on the urethra. The prostate can also become enlarged due to a condition called benign prostatic hyperplasia (BPH), which is non-cancerous.
The symptoms of benign (non-cancerous) enlargement of the prostate and prostate cancer are similar. They can include any of the following:
- difficulty passing urine and decreased force in the stream of urine
- passing urine more frequently than usual, especially at night
- the feeling of not completely emptying the bladder
- needing to rush to the toilet to pass urine
- blood in the urine or semen (this is not common)
- pain while ejaculating (this is rare).
In some cases, the first symptom of prostate cancer may be pain in the back, hips or legs. This is because prostate cancer can sometimes spread to the bones. Although may be many other reasons for the same.
3) Lung Cancer
Cancer in the lungs is called lung cancer. Lungs are the parts of our body that we use to breathe. They supply oxygen to the organs and tissues of the body. The lungs are divided into areas called lobes. The right lung has three lobes and the left lung has two.
The lungs are covered by a lining called the pleura which has two layers. The inner layer covers the lungs. The outer layer lines the ribcage and a sheet of muscle called the diaphragm that separates the chest from the upper tummy (abdomen).
Types of Lung Cancer
Doctors divide lung cancer into two major types based on the appearance of lung cancer cells under the microscope. The doctor makes treatment decisions based on which major type of lung cancer a person has. The two general types of lung cancer include:
- Small cell lung cancer: Small cell lung cancer occurs almost exclusively in heavy smokers and is less common than non-small cell lung cancer.
- Non-small cell lung cancer: Non-small cell lung cancer is an umbrella term for several types of lung cancers that behave in a similar way. Non-small cell lung cancers include squamous cell carcinoma, adenocarcinoma and large cell carcinoma.
Causes for Lung Cancer
Smoking causes the majority of lung cancers — both in smokers and in people exposed to secondhand smoke. But lung cancer also occurs in people who never smoked and in those who never had prolonged exposure to secondhand smoke. In these cases, there may be no clear cause of lung cancer.
Lung cancer usually doesn't cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer occur only when the disease is advance stage.
Signs and symptoms of lung cancer may include:
- A new cough that doesn't go away
- Changes in a chronic cough or "smoker's cough"
- Coughing up blood, even a small amount
- Shortness of breath
- Chest pain
- Losing weight without trying
- Bone pain
