Skeletal Disease

Dear Dance Captain,

As a result of osteoporosis, I am sorry to say that I must quit being a member of the dance crew. A year ago, I started experiencing moments of pain in my bones every once in a while. I did not have it checked until recently. The doctor said that I am diagnosed with osteoporosis, a skeletal disease where the cancellous bone loses calcium and the bones eventually become thin and may even disappear. Such a disease will restrict me from doing extensive exercises such as dancing. I am sorry to say that this is a farewell letter where I formally withdraw myself from the dance crew. I wish the team the best of luck in the future. I will always be there with you guys in spirit.

Sincerely,

Helen

What I learned about lung cancer

Lung cancer

- a disease where an uncontrolled cell in tissues of the lung continually grows and spread by metastasis.
-causes: smoking, second-hand smoking, air pollution
-symptoms: coughing, wheezing, shortness of breath, fatigue, unexplained weight loss, respiratory infections, hoarseness, and bloody mucus
- a chest x-ray will likely be performed to look for a cause of the respiratory symptoms
-sputum testing can also detect cancer in the lungs
-smoking is responsible for 85% of lung cancers
