Multicentre Aneurysm Screening Study. A randomised controlled study that assessed the effect of abdominal aortic aneurysm (AAA) screening on mortality in men.

Conclusion
Mortality from AAA in the cohort that had been screened was half that of those who had not been screened.

mass

A fundamental property of a quantity of substance related to the amount of matter present. Mass is not the same as weight, which is the force acting on a mass as a result of gravitation.

mass

the quantity of material in an object or body. Can be measured in terms of the force needed to accelerate it. Mass is measured in kg and is not to be confused with weight.

1. a lump or collection of cohering particles.
2. that characteristic of matter which gives it inertia.

mass-action ratios

inner cell mass
an internal cluster of cells at the embryonic pole of the blastocyst which develops into the body of the embryo.
lean body mass
that part of the body including all its components except neutral storage lipid; in essence, the fat-free mass of the body.
mass medication
(or immunization, or treatment, or prophylaxis, or testing, or screening) application of the procedure to all of the animals in the population, which may be as small as a herd or as large as a national herd. This sort of strategy has been used extensively and for many years in the control of diseases of animals, and has been the principal reason for the dramatic virtual eradication of the major plagues in many countries. The unintelligent extension of the strategy to the control of wastage caused by endemic disease has contributed most to the problem of residues of antibacterial drugs in the human food chain. See also mass medication.
mass number

Patient discussion about mass

Q. A lump in my armpit Hi, Last week after the shower I found a small painful lump in my right groin. I went to see a doctor and he prescribed me some antibiotics. I’ve been taking it for 5 days and the lump is still there. I’m 31, usually healthy and work-out in the gym regularly, don’t smoke or use drugs and don’t take any medications. Is that dangerous? Should I go and see another doctor?

A. What you describe sounds like enlarged lymph node. The first diagnosis that’s suspected in such case is an infection that makes it painful. The antibiotics you take need several more days to act, so currently it doesn’t sound suspicious. If the lump persist, it’d be wise to consult you doctor

Q. what is the regular body mass for a five three 11 year old

A. Here is a website that can help you calculate your childs body mass index(BMI). http://en.wikipedia.org/wiki/Body_mass_index

You cant always go by what those charts say though, because according to them I am overwieght. I'm 5'10 and I weigh 176 lbs and i am far from overweight. I would say that as long as your child is healthy and you can see that your childs weight isn't causing them problems then all is well. Hope this helps.

Q. What are the different type of breast lumps... what are the different type of breast lumps being confused by many as breast cancer and what are their symptoms?

A. Lumps i.e. the thickened area are formed when the tissues of the breast undergoes some changes. These changes are of two types that is benign (non-cancerous) conditions or cancer. A benign breast condition can be mistaken as cancer. Most of benign symptoms are the same as those seen in breast cancer but a cancer will be hard and a firm solid lump. Common type of lumps are:

1) General lump – which are like nodules and they may come and go soon.
2) Abscess lump – also called cyst are fluid fill sacs and may be due to infection.
3) Adenomas – abnormal growth of tissues, like fibroadenomas , it’s a benign tumor.
4) Atypical hyperplasia – fast growing abnormal cells
5) Blood clots – some time blood clot in the vein is mistaken for lumps and as cancer even.
