Fatigue is often confused with tiredness. Tiredness happens to everyone -- it's a feeling you expect after certain activities or at the end of the day. Usually, you know why you are tired and a good night's sleep solves the problem.
Fatigue is a daily lack of energy; it is excessive whole-body tiredness not relieved by sleep. It can last for a short time (a month or less) or stay around for longer (1-6 months or longer). Fatigue can prevent you from functioning normally and gets in the way of things you enjoy or need to do.
Cancer-related fatigue is one of the most common side effects of cancer and its treatment. It is not predictable by tumor type, treatment, or stage of illness. Usually, it comes on suddenly, does not result from activity or exertion, and is not relieved by rest or sleep. It is often described as "paralyzing" and may continue even after treatment is complete.
What Causes Cancer-Related Fatigue?
The exact reason for cancer-related fatigue is unknown. It may be related to the disease itself or its treatments.
The following cancer treatments are commonly associated with fatigue:
Chemotherapy. Any chemotherapy drug may cause fatigue, but it may be a more common side effect of drugs such as vincristine, vinblastine, and cisplatin. Fatigue usually develops after several weeks of chemotherapy. In some, fatigue lasts a few days, while others say the problem persists throughout the course of treatment and even after the treatment is complete.
Radiation therapy . Radiation can cause fatigue that increases over time. This can occur regardless of the treatment site. Fatigue usually lasts from 3 to 4 weeks after treatment stops, but can continue for up to 2 to 3 months.
Combination therapy. More than one cancer treatment at the same time or one after the other increases the chances of developing fatigue.
Bone marrow transplant. This aggressive form of treatment can cause fatigue that lasts up to one year.
Biological therapy. In high amounts, the biological substances used can be toxic and lead to persistent fatigue.
What Other Factors Contribute to Fatigue?
Tumor cells compete for nutrients, often at the expense of the normal cells' growth. In addition to fatigue, weight loss and decreased appetite are common.
Decreased nutrition from the side effects of treatments (such as nausea, vomiting, mouth sores, taste changes, heartburn, or diarrhea) can cause fatigue.
Cancer treatments, specifically chemotherapy, can cause reduced blood counts, which may lead to anemia, a blood disorder that occurs when the blood cannot adequately transport oxygen through the body. When tissues don't get enough oxygen, fatigue can result.
Medicines used to treat side effects such as nausea, pain, depression, anxiety, and seizures can cause fatigue.
Research shows that chronic, severe pain increases fatigue.
Stress can worsen feelings of fatigue. Stress can result from dealing with the disease and the "unknowns," as well as from worrying about daily accomplishments or trying to meet the expectations of others.
Fatigue may occur when you try to maintain your normal daily routine and activities during treatments. Modifying your schedule and activities can help conserve energy.
Depression and fatigue often go hand-in-hand. It may not be clear which started first. One way to sort this out is to try to understand your depressed feelings and how they affect your life. If you are depressed all the time, were depressed before your cancer diagnosis, are preoccupied with feeling worthless and useless, you may need treatment for depression.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased.
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.
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.
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.
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.
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.
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. Not getting enough sleep can hurt memory performance, health, and your mood.
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.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, drug abuse, and more. Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Neuroblastoma is a type of cancer that usually afflicts children under 5 years of age. The cancer forms in the adrenal glands, neck, chest, or spinal cord. Symptoms include bulging eyes, bone pain, dark eye circles, a lump in the neck, chest, or abdomen, weakness, or swollen stomach. Treatment depends upon the risk group, which is determined by staging, the child's age, tumor histology, and the tumor biology.
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.
Most often, caregivers take care of other adults who are ill or disabled. Less often, caregivers are grandparents raising their grandchildren. The majority of caregivers are middle-aged women. Caregiving can be very stressful, so it's important to recognize when it's putting to much strain on you and to take steps to prevent/relieve stress.
Anemia is a medical condition in which the red blood cell count
or hemoglobin is less than normal. The normal level of hemoglobin is generally
different in males and females. For men, anemia is typically defined as
hemoglobin level of less than 13.5 gram/100ml and in women as hemoglobin of less
than 12.0 gram/100ml. These definitions may vary slightly depending on the
source and the laboratory reference used.
What causes anemia?
Any process that can disrupt the normal life span of a red blood cell may cause anemia. Normal life span of a red blood cell is typically around 120 days. Red blood cells are made in the bone marrow.
Anemia is caused essentially through two basic pathways. Anemia is either caused:
by a decrease in production of red blood cell or hemoglobin, or
by a loss or destruction of blood.
As more common classifications of anemia (low hemoglo...
