disease process whereby cells
proliferate abnormally, ignoring
growth-regulating signals in the
environment surrounding the cell.

Malignant tumor
of glandular epithelium;
may produce mucin.
Breast, colon,
pancreas, prostate,
lung (non-small cell)
adenocarcinoma
Slow-growing, locally
invasive tumor derived
from basal cells of the
epidermis; rarely
metastasizes.
Sun-exposed skin
(face, neck, scalp)
basal cell carcinoma
Malignant tumor
originating
from squamous
epithelial cells, often
associated with chronic
irritation or sun exposure.
Skin, esophagus, oral
cavity, cervix, lungs.
squamous cell carcinoma
Malignancy from
the transitional
epithelium lining urinary
tract; linked to smoking
and occupational toxins.
Bladder, ureters, renal
pelvis.
transitional cell carcinoma
osteoblasts producing
immature bone (osteoid);
typically affects
adolescents and young
adults.
Long bones (femur,
tibia, humerus),
especially near growth
plates (metaphysis)
osteosarcoma
Malignant tumor
of cartilage-producing
cells; usually occurs in
middle-aged to older
adults.
Pelvis, femur, ribs,
shoulder girdle
chondrosarcoma
Vascular tumor
associated with HHV-8
infection; often occurs in
immunocompromised
patients (e.g., HIV/AIDS)
Skin, mucous
membranes,
gastrointestinal tract,
lungs
kaposi sarcoma
Malignant tumor
of smooth muscle cells;
aggressive and prone to
recurrence and
metastasis
Uterus,
retroperitoneum, deep
soft tissues
leiomyosarcoma
Rapid proliferation
of immature lymphoid
cells (lymphoblasts);
progresses quickly without
treatment.
Most common
in children, but can
occur in adults.
acute lymphoblastic leukemia
Malignancy of myeloid
precursor cells, leading to
accumulation of blasts in
the bone marrow and blood.
Common in adults,
especially >60 years;
associated with
radiation, benzene, or
chemotherapy
exposure.
acute myeloid leukemia
Slow-growing cancer
of mature B lymphocytes;
often indolent but can
transform into aggressive
lymphoma (Richter’s
transformation).
Most common in older
adults, especially males
>65 years.
chronic lymphocytic leukemia
