Breast cancer is one of the most predominant tumors among women and is caused by an abnormal growth of cells in the breast, and may even spread to other organs in the body. For the cure of breast cancer, its detection on time is very important and most widely used for this purpose tests are:-self-examination and clinical examination: self-examination is based on observation and breast palpation by women to detect irregularities. The auto scan is recommended on a monthly basis to all women over age 20. The same woman is capable of timely detecting injury when it does well and even though you don’t have a very big impact on mortality, lesions in the early stages of the disease are detected and the majority of breast cancers are detected by the same patient, discovering a lump or nodule. After the detection has to be a clinical breast examination with what should be a complete medical history of the patient. Medical history includes the family history of breast cancer and hormone status. Clinical breast examination is based on a physical examination of the breast with its palpation, overseeing addition nipples and armpits. With the physical examination of the breast are allowed to detect a high percentage of lesions not detected by mammography.

-Mammography: screening mammography, also called mammography, consists of a flat image of the breast obtained through exposure to X rays. You get two projections with three-dimensional information of the situation of the lesion, so if we want to do a mastografico study to detect possible injury to a woman, we take two pairs of images: a craneo-caudal and another medio-lateral – oblique, for each breast. Due to the structure of the breast becomes difficult to be able to see an abnormality, since all their fabrics are identical. In a mammogram can find us with: 1. injuries which could not have been palpable, smaller than 0.5 cm if you are nodules. 2 Calcifications can never become palpable by its small size. 3. Asymmetries in the mammary density.

4. Distortion of the structure of the gland. Nodules appear in two photos, blending with the glandular tissue. The calcifications are calcium crystal deposits very small only detectable by mammography. After x-rays and depending on the concentration of the malign particles, a biopsy of the suspicious part will be taken to make a pathological analysis of the sample and thus determine the extent of the injury.

The West

Doctors recommend that such patients with settling particles of ash to remain on the premises and use respirators in the open air. Volcanic eruption in southern Iceland, seriously disturbed inhabitants of the European continent. But scientists argue that the panic that arose from the volcanic eruption and the associated consequences, unfair and unreasonable because it is an ordinary event, which will not cause any serious climate change, will not strongly acid rain and will not affect adversely the health, as suggested by many. Some scientists said that a major volcanic eruption in Iceland may slow down growth global temperature for a couple of years, but will not reduce the anthropogenic increase of carbon dioxide in the atmosphere. Others argue that the eruption could not have a significant impact on the Earth's climate, although Last powerful eruptions often cause significant cooling of the planet, since particles of ash at high altitudes in the atmosphere blocking the sun's radiation.

Western scholars have noted that the effects of eruptions Eyyafyallayekyul volcano could be significant if the eruption will continue to go on, and ash emissions will rise into the stratosphere (ie, higher than now). Scientists fear that in this case, the cloud of volcanic ash may pose a risk to wildlife in Europe. Ash, who throws the Icelandic volcano Eyyafyallayekyul contains dangerous to livestock fluorine compounds, which can create serious problems for the European farmers. By the weekend the activity of waking up in the west of Iceland volcano Eyyafyallayekyul increased again. A column of ash above the volcano has increased, and a thick dark gray cloud has a height of 8.5 kilometers, while on Friday it was still high at 6 miles.
