Causes of Lung Lancer

Lung cancer is the major disease around every part of the country and this is increasing nowadays at greater speed. This is seen more common among men and women. There are only 2% of people surviving after diagnosing of cancer at its worst stage that is after spreading to most parts of the body through swelling. In the case of diagnosing at its early stage makes the people to survive for more than 5 years and more and the number of people survive in this case is 49%.

The lung is the easiest part from which it spreads to another part and in lungs there will be formation of some tumors and this also spreads to some other parts.  But there are also some other tumors which spread to other organs and these are not responsible for lung cancer. The best example for this kind of spreading in lungs is the prostrate lump which spreads through the bloodstream to the lungs but this is not a lung disease hence proper and well efficient scanning has to be done before treatment.

The main reason for occurring of cancer is due to the transformation of cells which undergoes many changes in growth and also lacks in basic habitual reins. These cells which behave differently from others form a group of cells and look different from where it arises and the tumors formed because of this kind of unnecessary growth of cells are very dangerous as they take oxygen, and nutrients from the distant cells which are not affected. This will cause the other cells to die and makes the whole system to work improperly in short period.

Lung cancer

Lung cancer is an infection caused by uninhibited cell growth in tissues of the human lung. This continuous cell growth in tissues might lead to disease metastasis. It also attacks the adjacent tissues and penetrates beyond the human lungs. The chief type of human lung cancers is carcinomas of the lung, resultant from epithelial cells. Lung cancer is the most common disease cause’s death first in men and second in women.

Diagnosis:

Carrying out a chest radiograph is the primary pace if a patient possesses symptoms of lung cancer. This may make helps doctors to know

1. Understandable and observable mass of cells in tissues.
2. Broadening of the Mediastinum
3. Atelectasis or collapse, consolidation or pneumonia, and pleural effusion.

If there is no radiographic result but the doubt and symptoms are high, a CT scan and bronchoscopes might provide the patient required information regarding the disease. CT-guided biopsy or Bronchoscopes are often used to categorize the tumor type. Irregularities in cells in sputum are associated with an increased risk of lung cancer. Sputum cytological examination along with further screening examinations might be used for early detection lung cancer in a patient.

There are significant differences between cancer that started in the human lungs, spreads all over the body parts and cancer that initiates somewhere in body, spreads into the lung.  The paths of infection during lung cancer are

1. Cancer that started in the lung and spreads all over the body parts.
2. Cancer that started in the other body parts and spreads into the lung.
3. Mesothelioma

The accurate cause of ovarian cancer is still unknown. However, there are some factors which contribute in raising the risk of developing ovarian cancer. Most of these seem to be linked to the working of the ovaries.

Like most other cancers, the risk of occurring ovarian cancer increases with the age. Apart from this factor, the risk of developing ovarian cancer may be amplified by

• A family background of cancer
• Infertility or having fertility treatment
• Comprising of breast cancer
• Using hormone replacement therapy (HRT)
• Having endometriosis
• Being obese or tall
• Using talcum powder
• Smoking

A family background of cancer

Most of the ovarian cancers occur due to gene alterations which develop during a woman’s life span and are not inherited. But about 1 out of 10 % ovarian cancer cases are resulted in the consequences of an inherited faulty gene. Faulty inherited genes which raise the risk of developing ovarian cancer include BRCA1 and BRCA2. These genes are also identified to increase the risk of breast cancer.

According to an online publication on Wednesday in the medical journal, ‘Lancet Oncology’ that with screening women for ovarian cancer enabled doctors to detect the disease almost two years prior, than in ordinary screening routine. Around 100,000 women are killed each year by ovarian cancer.

It has been a continuous search by the Scientists to find ovarian cancer occurrence earlier, which can save almost 90 percent of women. Whereas, currently women are diagnosed after the disease has spread leaving only 30 percent chances of survival.

To conduct the study 200,000 post menopausal women aged 50 to 74 were enrolled covering 2001 to 2005 records from U.K.  Out of these 100,000 women did not receive any screening tests, whereas almost 50,000 underwent blood test screening. In case of finding an abnormality the women then underwent an ultrasound. Rests of the 50,000 women were screened through ultrasound.

A new research has suggested that short-course radiation tracked by high-quality surgery could be the best way to treat operable rectal cancer. Surgery is considered as the best treatment for rectal cancer but it leaves the risk of cancer to be reappeared.

It was concluded from a former study that chemotherapy and radiotherapy can minimize the risk of cancer recurrence if they are applied after surgery. But radiotherapy is not considered as a good option because of it’s a high cost treatment and the long term complications like incontinence, sexual dysfunction and impaired bowel function can be occurred in its consequences.

Ovaries are the most important part of the female reproductive system. A woman contains two ovaries, situated at the both sides of the uterus.

The function of ovaries is to produce ovum that combine with the male sperm to produce fertilized egg called “zygote” and hormones which includes estrogen and

progesterone.

Ovarian cancer occurs when cells start to grow abruptly in an uncontrolled fashion, resulting in the formation of tumor. Each year, 23,000 new cases of ovarian cancer are being diagnosed in the U.S.

On average, 90 percent of cancer develops in the epithelium, the thin outer covering, of the ovaries. Unfortunately, ovarian cancer remains undiagnosed till it has spread in the abdomen.

The female ovaries are the key part of female reproductive system. These are situated in the pelvic region. The size of ovary is almost equal to a size of rich almond.

Ovaries, under the influence of endocrine system release the sex hormone i.e. estrogen and progesterone. The function of the ovaries is to release egg that travel through the fallopian tube to the uterus.

During the menopause, the ovaries stop egg production and release very minute level of hormones.

Ovarian cancer an overview

Almost all types of cancer grow at the cellular level. It’s a natural process that body form new cells through cell multiplication when the old cells die. These new cell replace the old dead cells and keep the body in proper working condition. If some how, the cells start to replicate without the need of the body and unable to replace the old cells, a mass of tissues called “tumor” would be produced.

Prevention is better than cure

Most types of skin cancer can be prevented if the risk factors and causes of skin cancer are taken seriously. However, there are some prevention tips to get maximum protection against developing skin cancer.

Avoid Long and Direct Sun Exposure

Exposure to the high intensity Ultraviolet rays of the sun because these are the key trigger of causing skin damages which lead towards skin cancer. These rays are on their maximum when the sun is on the peak especially from 10 am to 4 pm. It is a misconception that only long term exposure is harmful for the skin, short and non-regular contact with the intense sunlight may also increase the risk of skin cancer.

Hide the Sun Exposed Areas with Sunscreen

It is recommended that whenever go outside, apply sunscreens on the exposed parts of your body. Though sunscreens do not stop all the harmful UV radiation, they are a key factor of prevention from skin cancer. A broad-spectrum sunscreen, with sun protection factor (SPF) of at least 15, and having ingredients which have a better blocking capacity for UV rays, is highly recommended round the year. Sunscreens should be applied 30 minutes before going outside and reapplied after every two hours. After swimming and exercising, it should be used again. The usage of sunscreens must be taught to the children from childhood so that they can be prevented from sunburns or skin damages that can be resulted in skin cancer in the later stages of life.

Skin cancer is the type of cancer that is diagnosed and treated by a dermatologist, who decides that what kind of cancer treatment should be given to the victim of skin cancer or precancerous skin lesions. Normally, this decision is taken on the basis of cancer type, causes of skin cancer, its stage, location on the body, patient’s age, symptoms of the skin cancer and the patient’s overall health.

However the methods, generally used, are;

• Surgery
• Chemotherapy
• Radiotherapy
• Medications
• Under Studied treatments (limited to some types)

It’s a common thinking about skin cancer that it appears on the sun exposed areas of the skin, like face, scalp, lips, ears, neck, chest, arms and hands. But a lot of cases are reported with skin cancer, on the skin parts which are rarely exposed to the sun, palms, beneath finger nails, spaces between the toes or under the toe nails, and genital area. Moreover, skin complexion may very in case to case.

The appearance of symptoms depends on the type of skin cancer. In some types, it gradually developed and slowly showed itself while in other it can be appeared suddenly.

The symptoms, according to the type of skin cancer, have been mentioned as below;

Basal Cell Carcinoma

The most common type that does not metastasize is Basal Cell Carcinoma. It showed up itself in one of the of following symptoms;

• A translucent or waxy bump on the face, ears or neck
• Appearance of flat and scar like lesions, having brown or flesh like color, on the chest and back
