Just heard a close neighbor has blood and lymph cancer. how do we explain this condition to the kids?

Limit exposures: Cancer of the blood and lymph glands (leukemia and lymphoma) may be caused by a number of different molecular changes in the dna. Although there may not be just one "cause", we know that some contributing factors include family history of similar cancers, exposures to certain viruses, chemicals, and high radiation doses. Family should not be overly concerned and many treatments are effective.

Not catchey: Cancer of the blood and lymph nodes is a sporadic cancer, though it may have viral etiology in some cases. However, it is not transmissible from one person to an other. You should treat your neighbor with the same compassion as you would treat any other person with a serious illness.

I'm not sure what: "blood and lymph" cancer means, chronic lymphocytic leukemia? A lot depends on your kids age, and how close they are to the neighbor, but this is delicate in respecting your neighbors right to privacy, and your desire to educate or prepare your kids, for what, a discussion of mortality and death and dying or valiant battles with cancer? A mine field without full knowledge and skill.
