Millions of Americans alive today have been diagnosed with some form of cancer. So you needn't feel as if you're the first one to fight this battle. Cancer can strike anyone at any time. Some people with cancer were recently diagnosed, while others are receiving cancer treatment, are in remission or are considered cured.

The challenges you experience with your cancer may differ from those of other cancer patients. Your situation may present challenges that are physical, psychological, emotional or financial in nature. You may even have to deal with a combination of these factors, as have many others. Fortunately, there are steps you and your family and friends can take to help you during your battle with cancer and afterward.

1. Don't smoke.

This may be the most painfully obvious thing for you to do if you have been diagnosed with lung cancer. Smoking while undergoing treatment is likely to negate any progress you might make. Quitting smoking may not stop any new lung cancer that may be in development. However, it will make your lungs function better. This is important because while you are being treated, you will need that improved lung function to help you tolerate some of the effects that cancer treatment may have.

2. Be sure to exercise regularly.

Cancer and cancer treatment can take away a lot of your strength and stamina. Understandably, this takes away many people's motivation to keep active. Though it is likely you will be unable to keep the same regimen prior to treatment, you should still "get out there" to the best of your ability. Regular exercise that isn't too strenuous (such as walking) can help you retain a good deal of stamina and strength. This may help you endure the rigors of treatment more readily. It is generally recommended that, on most days, you try to exercise for at least 30 minutes whenever possible.
