Do What You Can to Ease Side Effects of Treatment for Carcinoma of Unknown Primary Origin
Here are some common side effects from treatment for carcinoma of unknown primary origin (CUP) and how to ease them. You may not have all of these. We've listed them in alphabetical order so you can find help when you need it.
Anemia (Low Red Blood Cell Levels)
Your doctor will take blood samples from you for blood tests throughout your treatment. One thing he or she is checking for is your red blood cell count. Red blood cells carry oxygen throughout the body. If your body does not have this oxygen, you may feel tired. If your red blood cell count is low, you have anemia. Decreased red blood cell counts can be caused by small amounts of blood loss, by chemotherapy, radiation, stem cell transplants, or by the cancer itself.
If your doctor tells you that you have anemia, take these actions to feel better.
Anxiety and Depression
Many people may feel blue, anxious, or distressed after being told they have cancer. These feelings may continue or come back throughout treatment All these feelings are a normal response to cancer. However, there are steps you can take to ease your mental stress.
Eating well during cancer treatment can help you maintain your strength, stay active, and lower your chances of infection. When you're being treated for cancer, a diet high in calories and protein is best. The problem is that side effects of treatment can change the way food tastes to you. It can also reduce your appetite.
Try these tips to stimulate your desire to eat.
If you can, eat foods high in protein several times a day. These foods include milk, cheese, cottage cheese, yogurt, meat, fish, eggs, beans, peanut butter, and nuts. Protein helps build and repair tissue. Cancer treatments cause you to use more protein than usual. A dietitian can help you learn what is best for you to eat and drink during your cancer treatment.
If you can, eat high calorie foods to help you maintain your weight. High-calorie foods include margarine or butter, sugar, honey, jams, jellies, cream cheese, dried fruit, gravies or sauces, mayonnaise, and salad dressing.
Get plenty of fluids to help control your body temperature and improve food elimination. In addition to water, apple juices, and other liquids, try gelatin, pudding, soups, frozen juice bars, and ice cream.
On days you don't feel like eating at all, don't worry about it. Try again the next day. If you find your appetite doesn't improve in several days, talk with your doctor or nurse. There are medications that can help increase your appetite.
Bruising and Bleeding
Chemotherapy can interfere with your body's ability to make certain blood cells called platelets. Platelets help stop bleeding when you get a cut or bruise. Without enough platelets, you may bruise or bleed too much. Tell your doctor if you notice these signs of excessive bleeding.
Small red spots under the skin
Signs of blood in your urine (reddish or pinkish color)
Black tarry stools or blood on the toilet tissue after a bowel movement
Bleeding from your nose or gums
Vaginal bleeding not related to your period
Headaches or changes in vision
A warm to hot feeling in the arms or legs
If your doctor tells you your platelet count is low, you have a condition called thrombocytopenia. Take these steps to help minimize your risk of bleeding.
Check with your doctor before taking any prescription, over the counter, or herbal medications. Some, such as aspirin, may further increase your risk of bleeding.
Be especially careful not to cut yourself when using knives, scissors, clippers, or other sharp tools.
This may be a side effect of chemotherapy or some pain medicines. Constipation may include difficult or infrequent bowel movements. It can range from mildly uncomfortable to painful. Taking pain medications can lead to constipation. So, take these preventive actions ahead of time. These same steps will give you relief if you are already constipated.

Eat low-residue, low-fiber foods such as those included in the BRAT diet (bananas, rice, applesauce, and toast).
Losing your hair is called alopecia. It can be upsetting because baldness is a visible reminder that you are being treated for cancer. Chemotherapy and radiation can cause hair loss. Keep in mind that your hair will probably grow back after treatment.
Try these coping tips.
Think about getting a wig, hat, or scarf before your hair loss starts. That way, you can get a wig that matches your hair, and you'll be ready with head coverings if you choose to use them.
Hot flashes may result from hormone therapy. To ease them, try these tips.
Because chemotherapy can reduce the number of white blood cells in your body, it can decrease your body's ability to fight off infection.

Call your doctor right away if you have any of these signs of infection.
Some types of chemotherapy and hormone therapy can cause menopausal symptoms. This may be because the drugs damage a woman's ovaries. Or they may prevent the release of the female hormone, estrogen. The result may be these menopausal symptoms, even if you've not yet reached menopause.
