Even if you do not smoke, you may be exposed to secondhand smoke. This type of smoke can come from:

• Someone breathing out smoke while smoking

• A burning cigarette, cigar, or pipe

You may also hear secondhand smoke called passive or involuntary smoke, tobacco smoke pollution, or environmental tobacco smoke.

There is no safe level of exposure to secondhand smoke. Even brief moments around secondhand smoke can harm a person’s health. And the risk of health problems is greater with more exposure.

Ascites is the buildup of fluid in the abdomen. The peritoneum is a membrane that surrounds the organs inside the abdomen that makes ascitic fluid. This fluid is normal in the body, but cancer can cause the peritoneum to produce too much of this fluid. This is called "malignant ascites" and it is often a sign of advanced cancer.

Calcium is a mineral found in different places in the body, including your blood. When you have more calcium in your blood than normal, doctors call it "hypercalcemia." It is a serious condition. Up to 30% of all people with cancer will develop a high calcium level as a side effect.

A high calcium level can be treated, and it is important to talk with your doctor if you experience any symptoms. Left untreated, a high calcium level can cause severe problems, like kidney failure, and it can even be life-threatening.
