What is the cervix?

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

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

If the EKG (Electrocardiography) shows that there is an acute heart attack (myocardial infarction), then the goal is to open the blocked artery as soon as possible and restore blood supply to the heart muscle.

When a heart attack strikes, the key thing to remember is that time equals muscle. The longer the delay in seeking medical care, the more heart muscle will be damaged. There is a window of opportunity to restore blood supply to the heart muscle by unblocking the affected heart artery. Treatments must be done in a hospital and include administration of clot-busting drugs to dissolve the clot at the site of the ruptured plaque and heart catheterization and angioplasty (in which the blood vessel is opened by balloon, often with adjunctive placement of a stent), or both.

Cancer (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, and do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not. The branch of medicine concerned with the study, diagnosis, treatment, and prevention of cancer is oncology.
