The average menstrual cycle is 28 days normal range days in length and menstruation normally spans days normal range days. The average amount of blood loss during a period is 30ml, equivalent to 2 tablespoons.

The medical term for abnormally heavy menstrual cycle is menorrhagia. Listed below are some of the indications that a woman is having abnormal uterine bleeding:. Bleeding that occurs after the menopause post-menopausal bleeding is usually abnormal and should always be evaluated by a physician.
Common causes of post-menopausal bleeding include the intake of hormones, thin and fragile lining of the uterus and vagina vaginal atrophyinfection, cellular changes in the vagina, cervix or uterus that could lead to cancer with time and cancer in the vagina, cervix or uterus. First your doctor will obtain a detailed history about your bleeding patterns. Here are some of the key pieces of information your doctor will need to know:. Hysteroscopy can be a valuable tool for the treatment of abnormal bleeding. Submucosal fibroids, i. Uterine polyps can also be removed in a similar manner. Smaller fibroids and polyps can be removed in the office without the need for general anesthesia, but larger lesions here need to be removed in the operating advantages and disadvantages of radiation therapy, either under general anesthesia or local anesthesia with sedation.
These procedures are often long and require significant dilatation of the cervix which can be very uncomfortable.
Radiotherapy - One World Essay
In addition, there is the potential for fluid overload as was discussed in an earlier chapter. A special type of hysteroscope, called a resectoscope, is wider than a standard hysteroscope and carries within it a channel that allows several specialized instruments to pass through. One of these instruments has a small wire loop at the end of it that is therxpy out of metal that is a relatively poor conductor of electricity. The loop is connected to a device that sends advantages and disadvantages of radiation therapy current through it. Because the electrical current has a hard time going through the poor conducting metal, the metal heats up significantly. This hot metal loop is then used to cut through a fibroid or a polyp inside the uterus.
Advanhages is almost link to cutting through hard butter with a hot knife. The fibroid or polyp are gradually cut into several little chips of tissue that are able to pass through the cervix.
Another recent invention uses a small morcellator, which is similar to an old fashioned apple corer that gradually chops up the fibroid or polyp and suctions the chips out of the uterus.

A disadvantage of using the metal loop is that since there is electricity running through the loop, it is not possible to use liquid such as saline that conducts electricity. The physician will therefore need to use a hypotonic water solution, which as discussed in the section on hysteroscopy, has a greater potential to cause problems with thinning of the advantages and disadvantages of radiation therapy and electrolyte imbalance.
The advantage of the morcellator is that it can be used in saline since there is no electricity there, however it is slower than the loop and is not as well suited for large fibroids. There are also special kinds of loops that can be used in saline solution. These are more expensive than the standard loops, so not all hospitals have them yet, but they are probably safer since there is less chance of an electrolyte imbalance compared with the standard loops.
Endometrial ablation essentially means destruction of the endometrium. This is typically done in women who have abnormal uterine bleeding were the workup is negative, rherapy. Some of the methods can also be used if there are small fibroids present. However, these methods cannot be used if there are large fibroids present or if the uterus itself is abnormally large.]
