Breast Cancer

By admin, 12:15 PM
Represents a problem of great importance medical social for being the pathology neoplastic more common in women, with high mortality rate between 45 and 55 years, reaching the 2nd place as the cause of death in most countries, with gradual increase in its incidence and mortality by increasing age.

The main risk factor is the personal history of breast cancer or background of the same in one or more direct relatives of first degree, especially if happened at early ages and bilateral, which makes the risk increase 3 to 10 times the normal population, with a risk of incidence of 13.1 % for white women in the USA and a 9.6 % for women afro-american.

The more early is the diagnosis, the greater the likelihood of healing, with opportunity for therapeutic procedures conservatives are not mutilantes, to lower costs for the patient and medical institutions involved.

METHODS OF DETECTING EARLY

1- SELF-EXAMINATION OR BREAST SELF.

It is very important in the early diagnosis of breast cancer, it is estimated that 65 percent of all the breast nodules are discovered by the breast self.

It is essential educate prior to the patients on its importance, objective basis and technique of self, so that the same becomes effective, taking into account that the mode of presentation more frequent breast cancer, is like a painless nodule, located mainly in the quadrant superexterno in a 50 percent of the cases, 20% to level the central area and in smaller proportion in the remaining quadrants breast.

It should do monthly in any woman who starts menstruating (menarche), about 10 days later in the same and in the women women once a month. The technique of breast self includes:

A: inspection bilateral mammary what makes the patient stop foot, compared to a mirror, looking asymmetries, eritemas, retractions or ulceraciones of mammary skin, areola or nipple. B: palpation bilateral mammary is performed by hand fills, which must be done in three positions, standing, sitting and lying (with a small pillow under the shoulder).

It must examine all of the breast in a systematic way, in different directions, transverse vertical, radio and circular, including armpit in search of areas induladas or nodules. C: compression of nipples to rule out presence of secretions.

The breast self should not be abandoned, although beyond availability of mammography, because some cancers not breast are detected by mammography, but if the palpation, patients who regularly as technical, manage generally a stadium early from his illness.

2- REVIEW CLINICO OF THE BREAST

The makes the doctor and includes:

a- interrogation (background hereditary, personal, clinical data on the current illness if any).

b- inspection of skin and complex areola – nipple.

c- palpation breast to assess in case of injury, location, size, characteristic of the tumor, including in addition the consideration of armpit, supraclavicular region, cervical and for-external, looking for possible adenopathy (nodes).

The American Cancer Society” recommends a clinical examination annual breast to all women over age 40 and every 3 years women under 40 years from the menarche (1era menstruation).

3-MAMMOGRAPHY

The fundamental importance of the mammography is in the early detection of breast cancer, the screening mamografico, achieves a reduction in mortality close to 30 per cent, proving to be significantly more accurate, that the clinical examination, in the detection of cancers small or minimal.

When the method is implemented in the form optima, sensitivity and specificity may exceed 90 per cent is reproducible and effective cost, associating with a quotient irrigation/reduced profit.

The review mamografico is simple and does not represent major drawback for the patient must be made in the first half of the menstrual cycle, bilaterally and in different projections (skull flow, mediolateral, oblique, etc.).

The mammography to detect minor injuries to 5 mm in diameter, in many cases carcinomas in situ, clinically hidden no palpable, which currently represent about 20 percent of all cases of breast cancer.

This early detection, amending the natural history of the disease, significantly improving survival and the quality of life of the patients. The reduction in mortality from breast cancer depends on the detection of injuries minimum, before that takes place the spread systematically.

The mammogram detected about 85 percent of the cancers of the breast, most of them can be viewed on mammography, before be palpable, identifies malignancies clinically hidden, as evidenced, with microcalcifications grouped, asymmetries in the breast density, architectural distortion or clinical lesions palpable, in the form of tumor masses densely espiculadas.

The risks of radiation associated to the study mamografico is generally considered insignificant. THE AMERICAN CANCER SOCIETY, recommends the study mamografico and clinical examination annual breast in any woman from the 40 years, in patients with high-risk family, it could initiate the detection mamografíca, at earlier ages, with a mammogram basis from the 35 years.

Colorectal Cancer

 It is the malignancy digestive more frequent in western countries, its incidence is highest in North America and Australia, somewhat lower in western Europe, lowest rates are recorded in South America, Asia and Africa.

The colorectal carcinoma is more prevalent in the urban population, in males of whites, the multiparity exerts a protective effect on women, although the tumors of location hayloft right, are more frequent in women, the incidence of colorectal carcinoma increases rapidly from the 40 years, peaking between 60 and 80 years.

The geographical difference in the incidence, seems attributable to the diet, deficit the fibers, excesses in the consumption of unsaturated fats, cholesterol and refined sugars, in a body with susceptibility genetically determined to develop injuries polypoid adenomatosas single or multiple, according to epidemiological evidence, clinics, morphological, genetic and molecular the point as precursors of the most colorectal carcinomas and on them can develop the alteration precancerous histological, called dysplasia, whose progression leads to a transformation tumor malignant.

Cuello Uterino Normal

It is the bottom and close the uterus that connects the body of the uterus with the vagina..

The uterus or matrix is a hollow organ, in the form of pear, aimed at preserving and nurture the product of conception (embryo – fetus) and to expel at the time, located on the part but lower abdomen of women (pelvis) between the bladder or rectum.

The cervix form a channel (endocervical canal) that leads into the vagina, which leads to the outside of the body.

The cervix, for the most extension, is covered by a epithelium cells flat, which are stratified as flakes, hence its name squamous epithelium, which continues in vagina and is the first image that has the gynecologist by placing the speculate intravaginal.

This portion of the cervix neighbor to vagina is called ectocervix or exocervix. The internal part, the cervix is called endocervix, which is the importance of a through so-called through endocervical. The endocervix this consists of a cylindrical epithelium columnar, with glands that produce clear mucus filante (mucus pre-ovulatory).

The union or “shock” of both epithelia (squamous epithelium ectocervical and columnar endocervical glandular) is called union escamo-columnar or processing area, located generally at the level of external hole of the cervix, being the place where originates 95 % of the cancers of the cervix.

The cancer refers to a group of more than 200 different diseases, all of them affecting the basic unit of the body THE CELL, normally cells divide to produce more cells, only when the agency needs, in the form of an orderly process and regulated that helps keep us healthy.

When the cells keep dividing when not needed, they generate a mass of tissue called TUMOR, which can be benign or malignant.

Fibroadenoma Mamario

The bening tumors are are not cancerous, not infiltrate to other tissues, nor does it spread to other parts of the body (metastasis), it is generally defined either of the adjacent structures can operate (dry) and not reappear (recurrences).

 

 

The benign tumors are not a threat to life.

The kidney cancer also known as kidney cancer affects more than 28,000 people in the United States, representing 2.5 percent to 3 percent of all the malignant tumors, being more frequent in men between 50 and 70 years. The malignant tumor classic is the renal cell carcinoma to clear cell. In children the type more frequent is the Wilms’ tumor.

The kidney cancer can be cured if detected early, (small tumor and located) however the symptoms often, there is no evidence until the tumor reaches large dimensions or da metastases (tumor invasion to lymph vessels or blood which vehiculiza these cells to different locations).

The renal cell carcinoma to clear cell can affect any portion of the kidney, usually appears in the poles kidney, dominate the upper pole, tend to be unilateral and unique, rarely bilateral.

Are masses tumor 3cm to 15 cm in diameter, white yellowish, sometimes with areas necroticas hemorrhagic, which have a tendency to invade the renal vein, with an extension of further to inferior vena cava, or by metastasis to lungs more than 50 per cent, bones 33%, liver 18 per cent to 35 per cent, adrenal gland 19%, kidney contralateral 7.5%, soft parts 8% to 36 per cent, central nervous system 1 percent to 8 per cent, have been described metastases in almost all organs and sites of the body, sometimes in locations very rare, as eyes, vagina, parpado, nose, distal end of finger.
