Positive pregnancy tests don't always indicate that conception has occurred. In some instances, false positives occur completely unrelated to pregnancy. Several medical conditions can cause the production of human chorionic gonadotropin, or HCG,...
Human chorionic gonadotropin, also known as HCG, is a hormone usually associated with pregnancy. A urine test can detect the presence of HCG, and a blood test measures the amount of HCG in the blood. This hormone is generated by the same cells...
Human chorionic gonadotropin, or hCG, is a hormone that is produced by a developing embryo during pregnancy. HCG is also an important marker for certain tumors. However, it is not known if elevated levels of hCG cause tumor growth or are a result...
Human chorionic gonadotropin, or hCG, is considered to be a pregnancy hormone. Non-pregnant women have low levels of the hormone, but it rises significantly during pregnancy. Specifically, it slowly rises after conception and peaks around nine to...
Human chorionic gonadotropin is the hormone that a woman's body begins to produce early in pregnancy. The hormone levels in the blood increase rapidly and then level out at around the 12th week of gestation. The hormone remains at a stable level...
Human chorionic gonadotropin, also called hCG, tests the amount of the hormone produced by the placenta in early pregnancy. In a healthy pregnancy, hCG levels rise in a relatively predictable pattern, doubling every 48 to 72 hours, although...
Testicular cancer is a rare but potentially serious problem that may develop in one or both of a man's testicles. Fortunately, testicular cancer is highly treatable and curable. According to the American Cancer Society, about 90 percent of...
Germ cell tumors are uncommon neoplasms that develop from the primitive cells that give rise to eggs and sperm. These tumors most commonly develop in the ovaries and testicles but may occur anywhere in the body, including the brain. Germ cell...
The esophagus is the long tube that carries food from your mouth to the stomach to be digested. Cancer of the esophagus was the third most common cancer of the digestive system in 2004, ranking just behind colorectal and pancreatic cancer,...
Testicular cancer occurs in men, typically around the age of 30 when normal cells in the testis change and become tumorigenic. The majority of testicular tumors originate from germ cells. While most testicular tumors respond favorably to radiation...
Human chorionic gonadotropin (hCG) is an amazing hormone that can signal the wondrous start of pregnancy or warn of the growth of a dangerous tumor. HCG can be detected in either blood or urine. Pharmaceutical preparations of hCG have been misused...
The esophagus is the portion of the digestive system that connects the mouth to the stomach. When esophageal cells become damaged, either due to smoke, acid burns or other causes, it can cause the cells in the esophageal lining to grow abnormally,...
Ovarian cancer is a gynecologic cancer that arises from the ovaries. There are various types of ovarian cancer, depending on where in the ovaries the cancer started, and how the cells look under the microscope. The American Cancer Society lists...
Human chorionic gonadotropin, hCG, normally appears in serum and urine during pregnancy, when the placenta produces the hormone. The presence of hCG triggers the continuing release of progesterone from the corpus luteum, the remnant of the...
The term "miscarriage" can refer to any type of pregnancy loss. Although many miscarriages occur naturally in the early stages of pregnancy, other types of losses occur later in pregnancy, or are medically or surgically induced due to problems...
Cytotoxic drugs are powerful chemotherapy medications used to kill cancerous cells. Different types of cytotoxic drugs interfere with varying cellular activities to induce cell death, with most disrupting some aspect of cell replication. If cancer...
Testicular cancer accounts for about 1 percent of all cancers in men and is the most prevalent type of cancer in younger men. With early detection and treatment, testicular cancer has a very high survival rate: About 95 percent of patients with...
If you have just been prescribed chemotherapy, it means your doctor wants you to take medications to treat your cancer. Your doctor might explain how it can check the spread or growth of cancer. It may be given alone or either before or after...
In 1956, doctors achieved the first cure using chemotherapy when they successfully treated a rare metastatic tumor called choriocarcinoma, according to the American Cancer Society, or ACS. Research continues to develop chemotherapy agents that...
The uterus or womb is usually about three inches long and hides behind the bones of the pelvis in the lower part of the abdomen. Under certain conditions, the uterus may become enlarged and can be felt arising from the lower part of the abdomen or...
Pregnancy levels are measured by testing blood or urine levels of beta hCG, or human chorionic gonadotropin, which is produced by cells that form the placenta. Only blood tests give an exact reading of hCG levels, and are often done serially to...
During pregnancy, the body begins to produce the hormone HCG, or human chorionic gonadotropin. It is secreted by the placenta following implantation of the embryo in the uterine wall. An HCG test is used to confirm pregnancy and later on it may be...
Human chorionic gonadotropin, or HCG, can be checked through both the urine and blood. Lab tests to check HCG levels are typically run to verify pregnancy. Yet the presence of HCG in the body can also be a marker for certain types of malignant...
Human chorionic Gonadotropin, or hCG, plays an important role in maintaining early pregnancies. Blood and urine pregnancy tests evaluate levels of hCG produced in the early stages of pregnancy by placental tissue. If you're having twins, triplets...
Human chorionic gonadotropin, or hCG, is a hormone produced by the placenta during a normal pregnancy. Simple home test kits, which detect the presence of hCG in urine, are effective soon after the pregnancy's conception. To learn the actual...
Menopause is defined as the date 12 months after a woman's last menstrual period. The average age for American women to reach menopause is 51 with a normal range of 39 to 59 years of age. At menopause, estrogen production slows. The earlier...
Human chorionic gonadotropin, or hCG, is a hormone that is produced during pregnancy by the developing embryo and the placenta. This glycoprotein hormone stimulates production of a hormone known as progesterone, which is required for the...
Testicular tumors are tumors that develop in the cells of the testicles, the egg-shaped male reproductive glands in the scrotum. There are numerous kinds of testicular tumors, but treatment with surgery, radiation and/or chemotherapy has produced...
