Among African Americans, myeloma is one of the top-10 causes of cancer death. UK
Myeloma is the 17th-most common cancer in the UK: around 4,800 people were diagnosed with the disease in 2011. It is the 16th-most common cause of cancer death: around 2,700 people died of it in 2012. Other animals
Multiple myeloma has been diagnosed in dogs, cats, and horses.In dogs, multiple myeloma accounts for around 8% of all haemopoietic tumors. Multiple myeloma occurs in older dogs and is not particularly associated with either males or females. No breeds appear overrepresented in case reviews that have been conducted. Diagnosis in dogs is usually delayed due to the initial nonspecificity and range of clinical signs possible. Diagnosis usually involves bone-marrow studies, X-rays, and plasma-protein studies. In dogs, protein studies usually reveal the monoclonal gammaglobulin elevation to be IgA or IgG in equal number of cases. In rare cases the globulin elevation is IgM, which is referred to as Waldenströms macroglobulinemia. The prognosis for initial control and return to good quality of life in dogs is good;  43% of dogs started on a combination chemotherapeutic protocol achieved complete remission. Long-term survival is normal, with a median of 540 days reported. The disease eventually recurs, becoming resistant to available therapies. The complications of kidney failure, sepsis, or pain can lead to an animals death, frequently by euthanasia. See also

A chemical burn occurs when living tissue is exposed to a corrosive substance (such as a strong acid, base or oxidizer) or a cytotoxic agent (such as mustard gas, lewisite or arsine). Chemical burns follow standard burn classification and may cause extensive tissue damage. The main types of irritant and/or corrosive products are: acids, bases, oxidizers / reducing agents, solvents, and alkylants. Additionally, chemical burns can be caused by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime. Chemical burns may:

need no source of heat
occur immediately on contact
not be immediately evident or noticeable
be extremely painful
diffuse into tissue and damage cellular structures under skin without immediately apparent damage to skin surface

Presentation
The exact symptoms of a chemical burn depend on the chemical involved. Symptoms include itching, bleaching or darkening of skin, burning sensations, trouble breathing, coughing blood and/or tissue necrosis. Common sources of chemical burns include sulfuric acid (H2SO4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO3), and hydrogen peroxide (H2O2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the skin, and silver nitrate produces noticeable black stains. Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion.
