Final answer:
In terms of treatment, depression does not directly impact lung cancer or increase the chances of survival. However, treating depression can improve the patient's quality of life and mental well-being.
Step-by-step explanation:
Lung Cancer and Depression
Lung cancer is a malignant tumor characterized by uncontrolled cell growth in lung tissues. It is the most common cause of cancer-related death in men and the second most common cause in women. However, depression and lung cancer are not directly linked in terms of treatment. Let's go through the options:
Improve her quality of life: Treatment for depression can help improve Margaret's quality of life by managing her symptoms and providing support. However, it doesn't directly impact her lung cancer.
Cure the cancer: Currently, there is no known cure for lung cancer in most cases. Treatment aims to manage symptoms, slow down the progression of the disease, and improve the patient's quality of life.
Increase her chances of survival: Treating depression alone does not increase the chances of survival from lung cancer. However, seeking appropriate treatment and support can help Margaret better cope with her cancer diagnosis.
Increase her level of depression: Treating depression aims to alleviate symptoms and improve the individual's mental well-being. It should not increase the level of depression.
In conclusion, while treatment for depression can improve Margaret's quality of life and mental well-being, it does not directly impact her lung cancer or increase her chances of survival.
