Cancer's Veil

Carcinoma, melanoma sick twins,
inside their innocuous hosts grin,
for surface tension brings no chagrin,
another, common diagnosis time will lend,
healthy cell structures to amend,
immune systems with guile befriend
In state of denial, journey begins,
signs not to the human eye hidden,
but worry has healthy mind forbidden
Asbestos, carbon dioxide, dioxin,
immune filters will certainly fend
Smoking, over eating, years of gin,
only near life's end, wages will append
Per chance, through a pore seeps a pathogen,
to rally antibody troops, always an antigen
discolored figment under skin
bright pigment, from allergen
a red rash can dry with benzine
yellowish splotch, need carotene
brownish bump, harmless toxin
black mole, surely of genetic origin
benign cyst, lacking a needed vitamin
purplish lesion, can cure with Neosporin
small lump, only a gland that's swollen
goiter, rarely takes malignant spin
