The short answer to your question is yes and no. Many studies have
been conducted on this subject, and no one could come with a single
answer. Just know that there is no study which could prove such
correlation, but it is "probable":

In 1980, laboratory findings showed that exposure to formaldehyde
could cause nasal cancer in rats. Since then, the question of whether
exposure to formaldehyde increases a person's risk of cancer has been
the subject of considerable controversy.

By 1987, enough evidence had been gathered to prompt EPA to classify
formaldehyde as a "probable human carcinogen" under conditions of
unusually high or prolonged exposure.

Multiple Myeloma is the most common primary bone cancer in adults
(generally in those older than 50) with an annual U.S. incidence of 3
to 4 cases per 100,000 people. It occurs with greatest frequency in
African-Americans and is very rare among Asians.

In Environmental Protection Agency (EPA) Integrated Risk Information
System (IRIS) documents, no such correlation between "multiple
myeloma" and formaldehyde/methanol has been reported (Please note that
formaldehyde is a suspected cause of cancer in this report, only there
is no mention of multiple myeloma specifically):

According to Cancer network, some causative factors that have been
suggested include chemical exposure to formaldehyde, together with
various other factors. But none of these associations has proven to be
statistically significant, and all have been contradicted by negative

Hope this helps
