Brest cancer

 Breast cancer can occur in women and rarely in men. It is the most common cancer in India for woman and rearly men affects too . Over 1 million patient comes across the world every year , with these . 

2nd most common cancer in woman after lungs cancer .

It treatable by a medical professional , requires medical diagnosis , and lab test and imaging test requires . 

its treatment depends on stages of cancer , it may consist chemotherapy , radiation, hormone therapy and surgery . 

 Uncontrolled growth of epithelial cells in the breast . 

# Don't cause pain or discomfort untill it spread to nearby tissue .

Cause :

 Breast cancer occurs when some breast cells begin to grow abnormally. These cells divide more rapidly than healthy cells do and continue to accumulate, forming a lump or mass. Cells may spread (metastasize) through your breast to your lymph nodes or to other parts of your body.

Breast cancer most often begins with cells in the milk-producing ducts (invasive ductal carcinoma). Breast cancer may also begin in the glandular tissue called lobules (invasive lobular carcinoma) or in other cells or tissue within the breast.

Researchers have identified hormonal, lifestyle and environmental factors that may increase your risk of breast cancer. But it's not clear why some people who have no risk factors develop cancer, yet other people with risk factors never do. It's likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment.

contradiction :

A personal history of breast conditions. If you've had a breast biopsy that found lobular carcinoma in situ (LCIS) or atypical hyperplasia of the breast, you have an increased risk of breast cancer

Inherited genes that increase cancer risk. Certain gene mutations that increase the risk of breast cancer can be passed from parents to children. The most well-known gene mutations are referred to as BRCA1 and BRCA2. These genes can greatly increase your risk of breast cancer and other cancers, but they don't make cancer inevitable.

  • Radiation exposure. If you received radiation treatments to your chest as a child or young adult, your risk of breast cancer is increased.
  • Obesity. Being obese increases your risk of breast cancer.
  • Beginning your period at a younger age. Beginning your period before age 12 increases your risk of breast cancer.
  • Beginning menopause at an older age. If you began menopause at an older age, you're more likely to develop breast cancer.
  • Postmenopausal hormone therapy. Women who take hormone therapy medications that combine estrogen and progesterone to treat the signs and symptoms of menopause have an increased risk of breast cancer. The risk of breast cancer decreases when women stop taking these medications.
  • Drinking alcohol. Drinking alcohol increases the risk of breast cancer.

Patient Shifting from O.T to Post Operative Care ( Part 2)

  Standard of Practice II It is the responsibility of the HCWs to safely transport a patient to the preoperative holding area or operating room. Confirm IV lines, indwelling catheters, monitoring system lines and drains, and any other lines are secure and patent, and IV bag and collection containers are hanging away from the patient’s head..  Ensure head, arms and legs are protected, adequately padded, and patient is comfortable as possible.  . The patient should be transported feet first; rapid movements, particularly when going around a corner should be avoided. Rapid movements, especially if the patient has received preoperative medications, can cause the patient to become disoriented, dizzy, and nauseated, and induce vomiting .. The staff person moving the transportation device should be positioned at the patient’s head in order to look forward for potential hazards. This also allows immediate access to the patient’s airway in case of respiratory distress or vomiting...

Anatomy and Physiology of aterial line

  Anatomy and Physiology The arterial pulse may be palpated in the extremities and the neck. With the knowledge of the contour of these vessels, the operator may easily identify the location of the artery. The anatomy of every site of insertion must be analyzed to determine the landmarks, the depth, the relationship to adjacent anatomical structures, and the size of the artery.   The radial artery is superficial in the thenar area of the wrist where the radial bone joins the metacarpal bones. There, the radial pulse is best felt slightly medial to the extensor tendons of the thumb. The radial artery is a preferred site of insertion. The ulnar artery is opposite to the radial pulse in the volar aspect of the wrist at the joint of the ulnar bone to the metacarpal bones. The artery divides into 2 branches, both of which join a similar division of the radial artery to form a rich, collateral network known as the deep and superficial palma...

the abdominal arota branches

  The abdominal aorta in a nutshell The abdominal aorta is a continuation of the descending thoracic aorta . It supplies all of the abdominal organs , and its terminal branches go on to supply the  pelvis and lower limbs . It also supplies the undersurface of the diaphragm and parts of the abdominal wall . It begins at T12 and ends at L4 , where it divides into the right and left common iliac arteries . It enters the abdomen through the aortic opening of the diaphragm , which is located beneath the median arcuate ligament between the crura of the diaphragm   at T12 . It is accompanied through the aortic opening by the azygos vein and the thoracic duct . It is located on th e posterior abdominal wall in the retroperitoneal space of the abdomen. It descends on the left of the inferior vena cava  (IVC) over the anterior surface of the bodies of the lumbar vertebrae and follows the curvature...
