Research on occupational causes of lymphoma

I'm trying to find scientific articles describing the occupational cause(s)
of lymphoma. Specifically, I'm trying to find links associating carcinogenic
vapours and lubricating oils used by welders and machinists.  I have found
some studies in PubMed, but I'm wondering what's the best way to go about
such a search. Are there any other sites that could yield results?

Searching in PubMed is really time consuming. Can anyone suggest key words
or some other strategy to make searching easier? Know any good sites that I
haven't thought of?

Thanks very much for any input.

Hi Karen, I'm kinda new to the group but not to lung cancers. Mom's brother
worked at the shipyard welding up here in Maine and he is diagnosed with
asbestosis and lung cancer. He also smoked for many years.The words you use
to search are important when getting the right places. try lymphoma welding
machinist in your search engines available on your homepage. Hope you
understand. I use Excite to search. I'll let you know if I find WebPages.
Take care of yourself and reach out here to vent or get info. See your dr if
you get depressed or overwhelmed because you can't help your son if you
don't stay healthy. The sick ones feel guilty about what their disease does
to all the family members.
Keep your chin up, it's a long haul this disease of cancer. Others here can
help you more I just wanted to respond since you sound
frustrated.........been there with my mom   :-)

Hi Lily Mae and thanks for your help!

Welding seems to be about the most hazardous occupation.40% greater chance
of getting lung cancer than the rest of us. I'm sorry about your uncle and
hope he does well with his treatment.

My son is a machinist/millwright who has also done a lot of welding as part
of his job. He suspects that the chemicals he came into contact with caused
his lymphoma, (cutting oils, welding fumes etc.) and he may be right.

You're quite perceptive to remind me to take care of myself. My son, who is
on chemo, has more energy than me these days.

Thanks for your help--anything is gratefully appreciated.

Karen

Hi Karen,

I'm not really sure what your end goal is; however, if it is to try to
determine if your son's illness is related to occupational exposure to
hazardous materials, the first thing that I would do in your shoes
(other that perhaps getting an attorney involved) would be to try to
find out exactly what hazardous materials he may have been exposed to.

I believe you may be in Canada so things may be a little different
than they are here in the US, but maybe not so different.  Anyway,
here in the US, I believe nearly all businesses are required to post
MSDS (Material Safety Data Sheets) for certain materials used in the
workplace.  I don't know exactly when an MSDS is required to be
posted; however, they are generally posted in a binder or book for any
materials that might pose a hazard to the worker.  If there is a
similar thing in your son's workplace, I would think that it would be
a great place to start to get info on the specific materials he may
have been exposed to.  One thing to consider though, it that it is
very likely that there are materials listed in the MSDS binder that
your son may not have used.

In your situation, getting access to an internal business document
like that (the MSDS binder) may not be too easy.  Maybe there are
coworkers that could get a list of the materials in the MSDS binder?
If a simple list of materials could be obtained, the individual  MSDS
are usually fetchable on the net.

A Google search on "welding supplies MSDS" will give you an idea of
the type of info that you can find in an MSDS.

Hope this helps and best of luck to you and your son.

Best regards,
Holden

Even if he was, it's unlikely have been documented (and certainly not by him).

Yes, then you get a list of possible materials from various websites.
Then redo the search with each material and "MSDS"

There's more here http://www.ilpi.com/msds/index.html

How she's ever going to do it is beyond me....(and then prove it).

Hi Karen, J,

I took a look at one of the websites that J suggested above and found
this section:

http://www.ilpi.com/msds/faq/partb.html#myrights

As it turns out,

"Under the OSHA standard 29 CFR 1910.1020, Access to Employee Exposure
and Medical Records, your employer is required to keep a record of
your exposure to hazardous materials at work. These "employee exposure
records" are to be kept at least 30 years after you terminate
employment. 1910.1020 allows employers to use MSDS's as part of or in
lieu of other sorts of documentation. As described in the previous
hyperlink, you or your designated representative (union rep, attorney
etc.) have a right to see your records at no cost and to obtain
copies."

So finding out what he has been exposed to _should_ be easy if the
above applies in Canada as well as in the US.  It will require being
up front with the employer though about what you are up to.

Karen, I don't really know if this is the way to go or not.  I guess
it's really up to you.  I don't know what the situation is with the
employer/former employer.  Right now, as a cancer patient, I'm very
dependent on my former employer for insurance coverage and would not
want to do anything to jeopardize that.  My situation is not one
though where my sickness is likely to be work-related.

Karen, take care and try to stay focused on what's most important to
you.

Best regards,
Holden

Hi J and Holden,

I don't think it would be too hard getting hold of an MSDS binder. If I
remember correctly, they are supposed to be readily available for any
employee. The Ministry of Labour would know anyway. But a problem I have is
that I'm doing research on a company that has closed--at least the branch
where my son worked.

I've already found a very long list of chemicals that welders and
machinists/millwrights are exposed to. It's unbelievable that more of them
aren't sick. Problem is, it's too long and has to be narrowed down to suit
the profile of items manufactured in an individual company. Oh well, at
least I know what has to be done!

Thanks for the great help and links.

Karen

Hi Karen,

Some of the fact sheets listed at the website below are relevant to
welding fumes and exposure to materials used in welding:

Hi again Karen,

Here's a couple links that may be useful on metalworking fluids:

Thanks Holden, I have already used your useful links. There's so much to go
through, unbelievable.

Thanks so much. I'll just keep pluggin' along here.
