To Cancer : Complementary and Integrative Therapies of Cancer.

Posts Tagged ‘Methods of Treatment’

Symptoms and signs of cancer depend on the type of cancer, where it is located, and/or where the cancer cells have spread. For example, breast cancer may present as a lump in the breast or as nipple discharge  while metastatic breast cancer may present with symptoms of pain (if spread to bones), extreme fatigue  (lungs), or seizures  (brain). A few patients show no signs or symptoms until the cancer is far advanced. However, there are some signs and symptoms, although not specific, which usually occur in most cancer patients that are fairly easy for the person to detect. They are as follows:

• Fever (no clear infectious source, recurrent or constant)

• Fatigue (not relived by rest)

• Weight loss  (without trying to lose weight)

• Pain (usually persistent)

• Skin changes (coloration, sores that do not heal,  wart changes)

• Change in bowel or bladder functions (including trouble swallowing  or constipation)

• Unusual bleeding (mouth, vaginal, and bladder) or discharge

• persistent cough or change in voice

• Lumps or tissue masses

Anyone with these signs and symptoms should consult their doctor.

Many cancers will present with some of the above general symptoms but often have one or more symptoms that are more specific for the cancer type. For example, lung cancer may present with common symptoms of pain, but usually the pain is located in the chest . The patient may have unusual bleeding, but the bleeding usually occurs when the patient coughs . Lung cancer patients often become short of breath, and then become very fatigued.

Because there are so many cancer types (see next section) with so many nonspecific and sometimes more specific symptoms, the best way to learn about signs and symptoms of specific cancer types is to spend a few moments researching symptoms of a specific body area in question. Conversely, a specific body area can be searched to discover what signs and symptoms a person should look for in that area that is suspected of having cancer. The following examples are two ways to proceed to get information on symptoms:

• Use a search engine (Google, Bing) to find links to cancer by listing the symptom followed by the term “cancer.” For example, listing “blood in urine  and cancer” will bring a person to web sites that list possible organs and body systems where cancer may produce the listed symptoms.

• Use a search engine as above and list the suspected body area and cancer (for example, bladder and cancer), and the person will see sites that list the signs and symptoms of cancer in that area (blood in urine being one of several symptoms listed).

In addition, if the cancer type is known (diagnosed), then even more specific searches can be done listing the diagnosed cancer type and whatever may be questioned about the cancer (symptoms, tumor grades, treatments, prognosis, and many other items).

Your own research should not replace consulting a health-care provider if you ae concerned about cancer.

Chemical or toxic compound exposures: Benzene, asbestos, nickel, cadmium, vinyl chloride, benzidine, N-nitrosamines, tobacco or cigarette smoke (contains at least 66 known potential carcinogenic chemicals and toxins), and aflatoxin

Ionizing radiation: Uranium, radon, ultraviolet rays from sunlight, radiation from alpha, beta, gamma, and X-ray-emitting sources

Genetics: A number of specific cancers have been linked to human genes and are as follows: breast, ovarian, colorectal, prostate, skin and melanoma.

It is important to point out that most everyone is exposed to cancer-causing substances (for example, sunlight, cigarette smoke, and X-rays) during their lifetime but many individuals do not develop cancer. In addition, many people have the genes that are linked to cancer but do not develop it. Why? Although researchers may not be able give a satisfactory answer for every individual, it is clear that the higher the amount or level of cancer-causing materials a person is exposed to, the higher the chance the person will develop cancer. In addition, the people with genetic links to cancer may not develop it for similar reasons (lack of enough stimulus to make the genes function). In addition, some people may have a heightened immune response that controls or eliminates cells that are or potentially may become cancer cells. There is evidence that even certain dietary lifestyles may play a significant role in conjunction with the immune system to allow or prevent cancer cell survival. For these reasons, it is difficult to assign a specific cause of cancer to many individuals.

Proving that a substance does not cause or is not related to increased cancer risk is difficult. For example, antiperspirants are considered to possibly be related to breast cancer by some investigators and not by others. The official stance by the NCI is “additional research is needed to investigate this relationship and other factors that may be involved.” This unsatisfying conclusion is presented because the data collected so far is contradictive. Other claims that are similar require intense and expensive research which may never be done. Reasonable advice might be to avoid large amounts of any compounds even remotely linked to cancer, although it may be difficult to do in complex, technologically advanced modern societies.

Treatment is dependent on type of cancer, location of the cancer, age of the patient, and whether the cancer is primary or a recurrence. One should look at the specific type of skin cancer (basal cell carcinoma, squamous cell carcinoma, or melanoma) of concern in order to determine the correct treatment required. An example would be a small basal cell cancer on the cheek of a young man, where the treatment with the best cure rate (Mohs surgery or CCPDMA) might be indicated. In the case of an elderly frail man with multiple complicating medical problems, a difficult to excise basal cell cancer of the nose might warrant radiation therapy (slightly lower cure rate) or no treatment at all. Topical chemotherapy might be indicated for large superficial basal cell carcinoma for good cosmetic outcome, whereas it might be inadequate for invasive nodular basal cell carcinoma or invasive squamous cell carcinoma. In general, melanoma is poorly responsive to radiation or chemotherapy.

For low-risk disease, radiation therapy (external beam radiotherapy or brachytherapy), topical chemotherapy (imiquimod or 5-fluorouracil) and cryotherapy (freezing the cancer off) can provide adequate control of the disease; both, however, may have lower overall cure rates than certain type of surgery. Other modalities of treatment such as photodynamic therapy, topical chemotherapy, electrodessication and curettage can be found in the discussions of basal cell carcinoma and squamous cell carcinoma.

Mohs’ micrographic surgery (Mohs surgery) is a technique used to remove the cancer with the least amount of surrounding tissue and the edges are checked immediately to see if tumor is found. This provides the opportunity to remove the least amount of tissue and provide the best cosmetically favorable results. This is especially important for areas where excess skin is limited, such as the face. Cure rates are equivalent to wide excision. Special training is required to perform this technique. An alternative method is CCPDMA and can be performed by a pathologist not familiar with Mohs surgery.

In the case of disease that has spread (metastasized), further surgical procedures or chemotherapy may be required.

Scientists have recently been conducting experiments on what they have termed “immune- priming”. This therapy is still in its infancy but has been shown to effectively attack foreign threats like viruses and also latch onto and attack skin cancers. More recently researchers have focused their efforts on strengthening the body’s own naturally produced “helper T cells” that identify and lock onto cancer cells and help guide the killer cells to the cancer. Researchers infused patients with roughly 5 billion of the helper T cells without any harsh drugs or chemotherapy. This type of treatment if shown to be effective has no side effects and could change the way cancer patients are treated.

A cream used to treat pre-cancerous skin lesions also reverses signs of aging, a study released in April 2009 indicated. In March 2010 academics from Dundee University in Scotland announced they had devised a new, less-painful method of treating skin cancer, which could be administered from the home.
