Cancer has become much more treatable in recent years due to new advances in medicine that often lead to earlier detection and more effective options for treatment. However, a diagnosis of cancer is still likely to be frightening, and it often brings up a wide range of difficult emotions and may significantly impact many areas of a person's life. The support of a mental health professional may help one cope with the psychological impact of cancer and may be an important aspect of the treatment process for both those who have cancer and their loved ones.
One-third of American women and nearly half of all American men will develop cancer in their lifetime. According to the American Cancer Society, avoiding certain risk factors such as tobacco and alcohol, maintaining an active lifestyle, and eating a varied diet that includes plenty of fruits and vegetables may help reduce the likelihood of one developing cancer, but there is no known method to prevent cancer.
One cause of cancer is genetics. It may be more likely for an individual to develop a certain type of cancer if one or more close relatives also have that type of cancer. Certain gene mutations can also be passed down through families, causing many members of a family to develop the same type of cancer. This is called family cancer syndrome, and genetic testing may help those who are at risk for an inherited cancer to become more informed about their risk for cancer and develop future health care plans if necessary.
Although sometimes cancer has no discernable cause, exposure to a known carcinogen, or cancer-causing agent, often makes it more likely that a person will develop cancer. Some known carcinogens are tobacco, alcohol, asbestos, steroidal estrogens, soot, some types of dyes, and radiation. A poor diet that contains large amounts of processed food and lacks a variety of nutrients has also been shown to be a risk factor for cancer, as has a lack of physical activity. Consumption of alcohol, especially excessive consumption, has been shown to increase one's risk for several types of cancer, including cancers of the mouth, throat, pancreas, liver, colon, and breast.
The National Cancer Institute recognizes more than 100 types of cancer. Cancer can affect almost any part of the body but may do so in a variety of ways. Some cancers grow and spread more quickly than others, and some cancers may not be as serious as others, especially when detected early. Different types of cancer cells also respond to treatment differently, which means that treating cancer often requires multiple approaches toward treatment. Cancer treatment might include surgery, radiation therapy, chemotherapy, targeted therapy, and others.
All cancerous tumors are malignant: they can invade tissue in other parts of the body, forming new tumors as they spread, in a process called metastasis. Surgery to remove the tumor may be sufficient treatment in some cases, but many cancers often require additional forms of treatment such as chemotherapy or radiation therapy. When cancerous tumors go undetected or untreated, they are very dangerous and are often likely to be fatal.
There is no cure for cancer. Many types of cancer are treatable, and partial and complete remission are both possible, but cancer may return at any time, a fact that may cause continued anxiety or worry even in those individuals who experience complete remission.
A diagnosis of cancer is likely to be frightening and life-altering, especially if the diagnosed type of cancer grows quickly or has already spread to other parts of the body. A person diagnosed with an advanced stage of cancer may begin to think about the end of life. Individual, family, and couples counselors can all provide support as a person attempts to better understand their diagnosis and come to terms with it. Some counselors are trained specially to help those diagnosed with cancer during their experience. Oncology social workers have received specialized training in the effects of a cancer diagnosis and typically provide counseling and education to those who have been diagnosed with cancer, and they may also help them better understand the health care system and their options, which is often a source of stress for many individuals with long-term illnesses.
Many doctors encourage their patients to seek out a therapist after a diagnosis of cancer. In counseling, many people are able to explore ways to cope with their diagnosis, manage any emotional concerns, such as depression, anxiety, or anger, that may result after receiving news of their illness, and discuss ways to address and cope with the life-altering aspects that may occur during the treatment process. Family counseling may be beneficial in helping the family members of those diagnosed with cancer learn ways to manage the varied emotions they may feel, such as anger, sadness, stress, and grief. Partners, spouses, and children may also be able to learn how to better support the member of the family with cancer, and family members can address any areas of conflict. Group therapy, where a person with cancer meets others who have cancer or other life-altering illness in a large counseling session, has also been shown to be helpful to many of those who live with cancer. Those having or who have had similar experiences may be an important source of information and support.
A subspecialty of oncology, psychosocial oncology, works to better understand the impact of cancer on those who have cancer and their families and explore and treat the effects that a diagnosis of cancer can have on mental health. Psycho-oncology has helped increase awareness of the mental health effects that may occur with physical illnesses and of the necessity for treatment of these concerns. Until the mid-1970s, there was such a stigma surrounding cancer that many times, those diagnosed with cancer were not even informed of their health condition. At the time, mental illness and other conditions that may have been helped by counseling or therapy were also stigmatized, and the connections between physical health and mental health were not widely understood or discussed. Now, while cancer is still a disease that is feared and mental illness is still often stigmatized, awareness regarding mental and emotional health needs has increased.
