Some patients lose their appetite and find it hard to eat
well. In
addition, the common side effects of treatment, such as nausea,
vomiting,
or mouth sores, can make it difficult to eat. For some
patients, foods
taste different. Also, people may not feel like eating when
they are
uncomfortable or tired.
Patients who eat well during cancer treatment often feel
better and have
more energy. In addition, they may be better able to handle the
side
effects of treatment. Eating well means getting enough calories
and
protein to help prevent weight loss and regain strength.
Doctors, nurses, and dietitians can offer advice for
healthy eating during cancer treatment. Patients and their families also may
want to read the National Cancer Institute booklet Eating Hints: Recipes and
Tips For Better Nutrition During Cancer Treatment
, which contains many
useful
suggestions.
When laboratory research shows that a new treatment method has
promise,
cancer patients can receive the treatment in carefully
controlled trials.
These trials are designed to find out whether the new approach
is both
safe and effective and to answer scientific questions. Often,
clinical
trials compare a new treatment with a standard approach so that
doctors
can learn which is more effective.
Researchers also look for ways to reduce the side effects of
treatment
and improve the quality of patients' lives. Patients who take
part in
clinical trials make an important contribution to medical
science. These
patients take certain risks, but they also may have the first
chance to
benefit from improved treatment methods.
Clinical trials offer important options for many patients.
Cancer
patients who are interested in taking part in a clinical trial
should talk
with their doctor. They may want to read What Are Clinical
Trials All
About?, a booklet that explains treatment studies and outlines
some of
their possible benefits and risks.
One way to learn about clinical trials is through PDQ, a
computerized
resource developed by the National Cancer Institute. PDQ
contains
information about cancer treatment and about clinical trials in
progress
all over the country. The Cancer Information Service can
provide PDQ
information to doctors, patients, and the public.
There are many types of ovarian cancer, epithelial carcinoma is the most common. Women with a family history of ovarian cancer have an increased risk of developing the disease. Some ovarian cancer symptoms include abdominal pain, nausea, diarrhea, constipation, and abnormal vaginal bleeding, however, they usually do not present until the disease has progressed. Early diagnosis is important for successful treatment.
In the U.S., more than 2,000 people are diagnosed with bone cancer every year. There are many types of bone cancer. The most common forms of bone cancer are osteosarcoma, Ewing's sarcoma, chondrosarcoma, malignant fibrous histiocytoma, fibrosarcoma, and chordoma. Pain is the most common symptom. Treatment usually involves surgery, chemotherapy, and radiation therapy.
Colon cancer is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
Skin cancer is the most common form of cancer
in humans. There are three main types of skin cancer; basal cell carcinoma and
squamous cell carcinoma (the nonmelanoma skin cancers), and melanoma.
Non-Hodgkin's lymphoma is cancer of the lymphatic system, a vital part of the body's immune system. Symptoms include swollen lymph nodes, fever, night sweats, coughing, weakness, chest pain, unexplained weight loss, and abdominal pain. Treatment depends on which type of non-Hodgkin's lymphoma you have, the stage of the cancer, your age, how fast the cancer is growing, and whether you have other health problems.
Cervical cancer is cancer of the entrance to the womb (uterus). Regular pelvic exams and Pap testing can detect precancerous changes in the cervix. Precancerous changes in the cervix may be treated with cryosurgery, cauterization, or laser surgery. The most common symptom of cancer of the cervix is abnormal bleeding.
Breast cancer is the most common cancer in women and the second most common cause of cancer death in women in the U.S. Symptoms include a lump in the breast or underarm area, nipple pain, change in breast size or shape, an inverted nipple, nipple discharge, and breast skin changes. Treatment may involve chemotherapy, radiation therapy, biological therapy, hormone therapy, or surgery.
Treatment for bladder cancer depends on the stage of the disease, the grade of the tumor, and the type of bladder cancer. Options for treatment include surgery, radiation therapy, chemotherapy, and biological therapy.
The term oral cancer includes cancer of the mouth (oral cavity) and the back of the mouth (oropharynx). Red and white patches inside the mouth, bleeding, loose teeth, pain upon swallowing, a lump in the neck, earache, and a sore on your lip or in your mouth that won't heal are all symptoms of oral cancer. Treatment for oral cancer depends upon the staging of the disease and usually involves surgery, radiation therapy, or chemotherapy.
Multiple myeloma is a form of cancer that develops in plasma cells, the white blood cells that make antibodies. Symptoms include bone pain, weakness, extreme thirst, nausea, frequent urination, and broken bones. Treatment of multiple myeloma depends upon the staging and symptoms of the disease.
Hodgkin's disease is a cancer of the lymphatic system with symptoms that include unexplained, recurring fevers, unexplained weight loss, itchy skin, and painless swelling of the lymph nodes in the neck, underarm, and groin. Treatment for adult Hodgkin's disease depends on the staging of the disease, the lymph nodes' size, and the health of the patient.
Prostate cancer is an uncontrolled (malignant) growth of cells in the prostate gland. Prostate cancer is the second
leading cause of death of males in the U.S. Prostate cancer is often initially
suspected because of an abnormal PSA blood test or a hard nodule (lump) felt on
the prostate gland during a routine rectal examination.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Barrett's esophagus occurs as a complication of chronic gastroesophageal reflux disease (GERD), primarily in white males. GERD refers to the reflux of acidic fluid from the stomach into the esophagus (the swallowing tube), and is classically associated with heartburn.
Testicular cancer symptoms include a painless lump or swelling in a testicle, testicle or scrotum pain, a dull ache in the abdomen, back, or groin, and a feeling of heaviness in the scrotum. Treatment for cancer of the testicles depends on the type of cancer (seminoma or nonseminoma), the stage of the cancer, and the patient's age and health.
The breast generally refers to the chest, however, more specifically, to the mammary gland. The mammary gland is a milk producing gland comprised largely of fat. Within the mammary gland is a complex network of branching ducts. The ducts exit from sac-like structures called lobules, which can produce milk in females. The darkened area around the nipple is called the areola. Common medical concerns in regard to the breast include breast lumps, breast cysts, breast cancer, and breast infections.
Male breast cancer accounts for 1% of all breast cancers, and most cases are found in men between the ages of 60 and 70. A man's risk of developing breast cancer is one in 1,000. Signs and symptoms include a firm mass located below the nipple and skin changes around the nipple, including puckering, redness or scaling, retraction and ulceration of the nipple. Treatment depends upon staging and the health of the patient.
Vaginal cancer is fairly uncommon. There are two types of vaginal cancer: squamous cell carcinoma and adenocarcinoma. Risk factors include being 60 or older, exposure to DES while in the womb, HPV infection, and having a history of abnormal cervical cells. Painful intercourse, pelvic pain, vaginal lumps, and abnormal vaginal bleeding or discharge are all symptoms of vaginal cancer. Treatment depends upon the stage of the vaginal cancer and may involve surgery, radiation therapy, chemotherapy, and the use of radiosensitizers.
Lifestyle changes, a healthy antioxidant-rich diet, exercise, and weight reduction can help reduce a woman's risk of developing breast cancer. It's important to be aware of how risk factors such as family history, lifestyle factors, breast conditions, radiation therapy, and hormonal factors may influence your chances of developing breast cancer. Mammography and breast self-examinations are crucial steps in breast cancer prevention.
