The cervix is the name for the lowest part of the uterus. The uterus is an organ that only women have, and it is where a baby grows and develops when a woman is pregnant. During pregnancy, the uterus has an enormous increase in size. When a woman is not pregnant, the uterus is a small, pear-shaped organ that sits between a woman’s rectum and her bladder. The cervix connects the uterus with the birth canal (the vagina). The cervix can both be visualized and sampled by your doctor during a routine pelvic examination in his or her office.
The narrow neck of the uterus is called the cervix. This is where cervical cancer may develop
Parkinson’s disease (PD) belongs to a group of conditions called motor system disorders, which are the result of the loss of dopamine-producing brain cells. The four primary symptoms of PD are tremor, or trembling in hands, arms, legs, jaw, and face; rigidity, or stiffness of the limbs and trunk; bradykinesia, or slowness of movement; and postural instability, or impaired balance and coordination. As these symptoms become more pronounced, patients may have difficulty walking, talking, or completing other simple tasks. PD usually affects people over the age of 50. Early symptoms of PD are subtle and occur gradually. In some people the disease progresses more quickly than in others. As the disease progresses, the shaking, or tremor, which affects the majority of PD patients may begin to interfere with daily activities. Other symptoms may include depression and other emotional changes; difficulty in swallowing, chewing, and speaking; urinary problems or constipation; skin problems; and sleep disruptions. There are currently no blood or laboratory tests that have been proven to help in diagnosing sporadic PD. Therefore the diagnosis is based on medical history and a neurological examination. The disease can be difficult to diagnose accurately. Doctors may sometimes request brain scans or laboratory tests in order to rule out other diseases.
At present, there is no cure for PD, but medications or surgery can provide relief from the symptoms.
What is HIV ?
A chronic, slowly progressive infectious disease caused by human immunodeficiency virus (HIV), which enters the body and slowly destroys the human immune system. With the virus infected people known as HIV – infected, HIV-seropositive or HIV viruses.
HIV and AIDS are not the same thing, but the virus can lead to the disease. Watch this video and learn more about HIV and AIDS
Causes of seizures in children – birth traumas, infections, congenital abnormalities, high fevers. Causes of seizures in middle years – head injuries, infections, alcohol, stimulant drugs, medication side-effects. Causes of seizures in elderly – brain tumors, strokes.

Health insurance is insurance that pays for medical expenses. It is sometimes used more broadly to include insurance covering disability or long-term nursing or custodial care needs. It may be provided through a government-sponsored social insurance program, or from private insurance companies. It may be purchased on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. In each case, the covered groups or individuals pay premiums or taxes to help protect themselves from high or unexpected healthcare expenses. Similar benefits paying for medical expenses may also be provided through social welfare programs funded by the government.
By estimating the overall risk of healthcare expenses, a routine finance structure (such as a monthly premium or annual tax) can be developed, ensuring that money is available to pay for the healthcare benefits specified in the insurance agreement. The benefit is administered by a central organization such as a government agency, private business, or not-for-profit entity
There are three types of common radiotherapies used as prostate cancer treatments: the conventional electron beam radiation therapy (EBRT), and the newer 3-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation (IMRT). Electron beam radiation therapy was the first external radiation therapy used as a prostate cancer treatment. The type of particle used for these three therapies is called photons which have no charge and no significant mass. Photons are the same type of energy used in diagnostic x-rays.
3D-CRT is an advanced form of EBRT, and IMRT is an advanced form of 3D-CRT. Therefore, the way radiation oncologists prepare their patients for the procedure is similar. Patients receiving external radiation therapy usually receive treatments Monday through Friday for 5 to 9 weeks depending on the doctor’s prescription. Radiotherapy usually begins with a CT (computer tomography) scan of the prostate gland and the surrounding organs. The CT scan takes a 3D-picture of the prostate gland and the surrounding organs and a team of radiation physicists and dosimetrists plan a target area for the radiation beam. The target area conforms to the shape of the patient’s prostate gland and, to ensure correct positioning, the patient will have his target area marked with permanent ink. The team will further use alignment lasers to direct the radiation beam. The patient, who is lying on his back, receives therapy from the linear accelerator which moves up, down, and around to hit the target area from different angles.
The prostate is a glandular organ present only in males. Only men develop prostate cancer.
The prostate is normally about 3 cm long (slightly more than 1 inch) and lies at the neck of the bladder and in front of the rectum.
The prostate surrounds the urethra, which is a tubular structure that carries sperm and urine out of the penis.
It produces a thin, milky fluid that is added to the sperm at the time of ejaculation.
Older men often have an enlarged prostate, which is a noncancerous condition called benign prostatic hypertrophy (BPH) that causes urinary symptoms.
Cancer occurs when normal cells undergo a transformation in which they grow and multiply without normal controls.
As the cells multiply, they form a mass called a tumor.
Tumors are cancerous only if they are malignant. This means that they invade neighboring tissues because of their uncontrolled growth.
They may also travel to remote organs via the bloodstream.
This process of invading and spreading to other organs is called metastasis.
Tumors overwhelm surrounding tissues by invading their space and taking the oxygen and nutrients they need to survive and function.
Almost all prostate cancers arise from the secretory glandular cells in the prostate. Cancer arising from a glandular cell is known as adenocarcinoma. Therefore, almost all prostatic cancers are prostatic adenocarcinomas.
In the United States, cancer of the prostate is a common malignant cancer in men, second only to lung cancer. About 200,000 new cases are diagnosed each year, and about 30,000 men die of the disease each year.
Prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive system
What is asbestos?
Asbestos is the name given to a group of minerals that occur naturally in the environment as bundles of fibers that can be separated into thin, durable threads. These fibers are resistant to heat, fire, and chemicals and do not conduct electricity. For these reasons, asbestos has been used widely in many industries.
Chemically, asbestos minerals are silicate compounds, meaning they contain atoms of silicon and oxygen in their molecular structure.
Asbestos minerals are divided into two major groups: Serpentine asbestos and amphibole asbestos. Serpentine asbestos includes the mineral chrysotile, which has long, curly fibers that can be woven. Chrysotile asbestos is the form that has been used most widely in commercial applications. Amphibole asbestos includes the minerals actinolite, tremolite, anthophyllite, crocidolite, and amosite. Amphibole asbestos has straight, needle-like fibers that are more brittle than those of serpentine asbestos and are more limited in their ability to be fabricated
Smokers who are also exposed to asbestos have a greatly increased risk of lung cancer
