ALL (also called acute lymphocytic leukemia) is an aggressive type of leukemia characterized by the presence of too many lymphoblasts or lymphocytes in the bone marrow and peripheral blood. It can spread to the lymph nodes, spleen, liver, central nervous system (CNS), and other organs. Without treatment, ALL usually progresses quickly.
Signs and symptoms of ALL may include the following:
Weakness or fatigue.
Fever or night sweats.
Bruises or bleeds easily (i.e., bleeding gums, purplish...
Is there really such a thing? The surprising answer is yes. Some people
really do smoke just a few cigarettes a week. But if you think you're one of
them, think again.
Researchers call them "chippers." There's much to learn from this.
The term is a slang word for heroin users who try to avoid addiction by
infrequent use of small drug doses. It's not a strategy that often works -- for
heroin, or for nicotine, says Elizabeth E. Lloyd-Richardson, PhD, assistant
professor of psychiatry and health behavior at Brown University, Providence,
R.I. She's an expert in adolescent and college-age smoking behavior.
"This is absolutely not a good thing to try," Lloyd-Richardson tells
WebMD. "We certainly know the health risks associated with smoking. At this
point we have not determined a safe amount of smoking. Research also suggests
that particularly with adolescents, they often are kind of lulled into this
sense they can smoke a little in social situations and then can quit when they
go to college or get a job. And we don't actually see that happening that much.
Overall, these smokers end up smoking for many, many more years than they
It's not entirely a bad thing for a person to try to smoke just a little
instead of a lot, says Jack E. Henningfield, PhD, professor of psychiatry at
Johns Hopkins Medical School.
"The good side is if a person is honest, and truly is only smoking in
social situations -- and those are not daily situations -- that person
is at a lower level of dependence," Henningfield tells WebMD. "If
properly motivated, such people should be able to quit completely. And they
should. A person wouldn't go out to their car four times a week and inhale
exhaust fumes. But that is the health equivalent of smoking cigarettes four
times a week."
