Turmeric and cancer

Friday, August 6th, 2010

turmeric and cancerSome studies have found that postmenopausal women who received estrogen and progestin for treatment, are at increased risk of breast cancer. So say in natural medicine.

But a new study has shown a possible answer: the spice turmeric. This Indian spice popular use seems to reduce the risk of this cancer.

Treatments Of Basal Cell Carcinoma

Treatments Of Basal Cell Carcinoma

How is it treated?
* Surgical excision, if possible, is the preferred technique because it allows to remove the tumor in its entirety and make a subsequent histological study to determine if the edges of the surgical specimen are free. A variant of this technique is Mohs microsurgery, which is performed histological study of the piece on the operative act itself so as to determine whether or not it is necessary to continue to expand the margins of excision, is a technique used primarily when affect areas involved such as the eyelids. It is probably the treatment of choice in the forms sclerodermiform.
* Curettage and electrocoagulation: This technique is removal by curette, based on the greater friability of the tumor relative to healthy skin. Subsequently, the treated area is electrocoagulation to remove debris. The drawback of this technique is unable to confirm the total removal.
* Cryosurgery (liquid nitrogen) can be used in small lesions, but does not allow histological confirmation or determine if excision has been complete.
* Radiation therapy: Their primary indications are elderly, large lesions, when surgical treatment fails or if it’s difficult.
* Topical cytotoxic agents: 5-fluorouracil can be used only in the treatment of superficial basal cell carcinoma.
* Laser: This is a difficult treatment availability and does not allow histological control. So although it should not be a treatment of choice may be used in selected cases, as the Gorlin syndrome. CO2 can be used or photodynamic therapy.
* Imiquimod: This emerging drug was initially approved for the treatment of genital warts. It has an immunomodulatory effect by stimulating the immune response of the individual in charge of eliminating viral injury. There are also several studies that prove antitumor action. It has been recently approved in Europe for use in the treatment of superficial and nodular basal cell carcinomas of small size. The disadvantages are that we have focused on histological control of the removal of the tumor and its high irritant.

Clinical forms of basal cell carcinoma

Clinical forms of basal cell carcinoma

Basal cell carcinoma is characterized by very heterogeneous from a clinical standpoint, which can sometimes make diagnosis difficult. Its most common location is on the face. It has a slow growing and painless, although as noted earlier, the evolution can produce invasion and destruction of adjacent structures.

The most common presentation is as pearly papule with teleangiectasia on its surface, which tends to be localized in the medial canthus, nose, or forehead. Corresponds to 95% of basal cell carcinomas. In the evolution may ulcerate in the center of the lesion, although the edges remain pearly papules features. In some cases the ulceration occurs early and massive way, then called ulcus Rodens, a less frequent but more aggressive.

Other clinical forms are:
* Basal Cell Carcinoma sclerodermatous: Board shiny smooth, flat and sometimes depressed slightly ill-defined borders resembling morphea. Sometimes we can see the look on their margins teleangiectasia pearl and typical of this tumor. Characteristically, the growth in depth of these lesions over the limits that we see clinically.
* Superficial Basal Cell Carcinoma: a raised red plaque with scaly surface, which is typically located in the trunk. Sometimes it can appear as multiple lesions in this case being generally related to previous exposure to arsenic.
* All clinical forms of basal cell carcinoma can appear as pigmented lesions, making it difficult differential diagnosis with melanoma.

Basal Cell Carcinoma

Thursday, July 22nd, 2010

The known risk factors are:
* Chronic sun exposure
* Phototype skin I / II
* Treatment with radiation therapy
* Ingestion of arsenic chronically
* Immunosuppression
* Genetic predisposition:
– Gorlin syndrome or multiple basal cell nevus
– Bazex syndrome
– Xeroderma pigmentosum

Diagnosis and differential diagnosis
Preliminary diagnosis is clinical basal cell carcinoma. It is essential to know the existence of other types of presentation in addition to the characteristic pearly papule. Definitive diagnosis is by histological confirmation by biopsy.

The differential diagnosis of basal cell carcinoma is wide due to the diverse clinical manifestations. Arises mainly with the following entities:
* Actinic Keratosis
* Seborrheic Keratosis
* Tumors of skin appendages
* Giant Melanocytic
* Melanoma
* Bowen’s Disease
* Squamous cell carcinoma

Treatment of Leukemia Cancer

Thursday, March 25th, 2010

leukemia cancerAs this type of leukemia is common in patients of advanced age, often in ways not very aggressive and low capacity of treatment to prolong life, it is essential first to decide whether treatment is necessary or not.

It should deal with cases where the disease is active, ie who has anemia or thrombopenia resistant, lymphadenopathy massive or rapid growth, constitutional symptoms or lymphocytosis rapidly progressive.

Patients who are in stage 0 of Rai, the prognosis is very good, they are not usually given any treatment because there is no cure.

These patients often have more than 60 years and what they usually do is carefully monitored. More than half of them live, at least ten years after diagnosis of the disease.

For stages I and II, intermediate risk, no treatment is required immediately if there are no symptoms. When symptoms associated with the disease, use of chemotherapy with chlorambucil or cyclophosphamide, is usually given along with prednisone.

Other medications used are similar to purines, such as fludarabine, which are drugs that interfere with DNA synthesis, producing a selective decrease of T cells and therefore a severe immunosuppression. This medicine, in chronic lymphocytic leukemia, get referrals full or partial in 50% of cases.

Symptoms and Diagnosis of Leukemia Cancer

Tuesday, March 23rd, 2010

chronic leukemiaIn its initial stage, these leukemias are asymptomatic in 60% of the cases are detected only after performing a routine laboratory, which is an increase in lymphocytes.

As the disease progresses, we see the presence of lymphadenopathy and organomegaly to increase as greater the number of lymphocytes.

You also have other symptoms caused by the decrease in the number of other blood cells such as red blood cells and platelets.

The anemia does not occur in the first stage of the disease, but when the bone is affected by the invasion of lymphocytes, there is a decrease of red blood cells. Anemia produces pallor, fatigue, shortness of breath and tachycardia.

Sometimes bleeding is shown by the decrease in platelets. They are serious when the platelet count is below 10,000 per ml and will not happen if the decline is not very intense (50,000 per ml).

It may not be reached to produce a large hemorrhage and that lack of platelets occurs only bruising, bleeding gums or nosebleeds mild.

What are Chronic Leukemia?

Saturday, March 20th, 2010

chronic leukimiaThere are several types of chronic leukemia cells depending altered. On the one hand, there are chronic lymphoproliferative syndromes, and other chronic myeloproliferative disorders.

Chronic lymphoproliferative syndromes are a series of diseases caused by the uncontrolled growth (neoplastic nature) of mature-looking cells that present with a peripheral blood involvement.

Most of these syndromes are caused by abnormal growth and proliferation of B lymphocytes Chronic lymphocytic leukemia is, in these syndromes, the most common in Western populations.

Chronic myeloproliferative syndromes are due to an alteration of stem cells or blood-forming, which is used to increase the number of precursor cells and mature cells derived from them. Among these syndromes, is chronic myeloid leukemia.

COMPOSITION OF THE BLOOD

The bone marrow, which is inside the bones, is composed of hematopoietic cells by fat cells and supporting tissues.

Hematopoietic stem cells reproduce continuously to form new cells. Some of these, will turn new stem cells and others, when mature, will become red blood cells, white cells and platelets.

Red blood cells, erythrocytes or red blood cells are responsible, through a component called hemoglobin, carry oxygen from the lungs to tissues and carbon monoxide in the opposite direction. Red blood cells are produced in the bone marrow at a rate of about two million per second. If they decrease, anemia will occur and will not be enough oxygen to the tissues.

Detection and Symptoms of Gynecological Tumors

Tuesday, March 16th, 2010

gynecological cancerThe most common symptom of cancer of the uterus and cervix is abnormal vaginal bleeding. At first, this bleeding is a very watery fluid in which the amount of blood will be higher.

Be careful not to confuse it with the onset of menopause, should coincide with this period of life. Other signs are pain during sex or urination, or a general discomfort in the pelvic area.

The problem of ovarian cancer is that these symptoms come too late, so when it is detected, the disease is already at a very advanced and very difficult to solve.

Among the most used techniques to detect cancers of the female reproductive tract include:

* The pelvic examination: the doctor is done manually and includes the uterus, vagina, ovaries, fallopian tubes, bladder and rectum. In the event that it detected an anomaly in the shape or size of these bodies would be to use imaging techniques such as ultrasound.

* According to a study published in the Journal of the American Medical Association, it is advisable to combine the Pap smear with a test for human papillomavirus, and that 93% of women with cancer of the cervix are infected with this virus. There is also a vaccine that has shown positive results when it comes to protecting women from contracting it. Doctors recommend getting vaccinated before starting a sexual activity.
