Benign and Malignant
Tumors
Neoplasm
•is an abnormal growth of tissue.
•Also known as a tumor
•(meaning "new formation")
Definition of Tumor
•“A tumor is an abnormal mass of tissue,
the growth of which exceeds and is
uncoordinated with that of the normal
tissues and persists in the same excessive
manner after cessation of the stimuli
which evoked the change”
Classification of a tumor:
1. Benign tumor
2. Malignant tumor
Benign tumors
• are non-malignant/non-cancerous tumor.
• A benign tumor is usually localized, and does
not spread to other parts of the body.
• Benign tumors are typically slow-growing.
• Most benign tumors respond well to treatment
and They often have well-defined borders, so
surgical removal can be an effective treatment.
• However, if left untreated, some benign tumors
can grow large and lead to serious disease
because of their size.
• Benign tumors can also mimic malignant tumors,
and so for this reason are sometimes treated.
• benign tumors can be serious if they press on
vital structures such as blood vessels or nerves.
• sometimes they require treatment and other
times they do not.
Malignant tumors:
• cancerous growths.
• usually fast-growing,
• They are often resistant to treatment, may spread
to other parts of the body and they sometimes
recur after they were removed.
Benign and malignant tumor comparison
COMPARISON
Cell Characteristics
•Benign
•Well-differentiated
cells that resemble
normal cells of the
tissue from which the
tumor originated
•Malignant
•Cells are
undifferentiated and
often bear little
resemblance to the
normal cells of the
tissue from which
they arose
Mode of growth
•Benign
•Tumor grows by
expansion and does
not infiltrate the
surrounding tissues;
usually encapsulated
•Malignant
•Grows at the
periphery and sends
out processes that
infiltrate and destroy
the surrounding
tissues

Rate of growth
•Benign
•Rate of growth is
usually slow
•Malignant
•Rate of growth is
variable and depends
on level of
differentiation; the
more anaplastic the
tumor, the faster its
growth
Metastasis
•Benign
•Does not spread by
metastasis
•Malignant
•Gains access to the
blood and
lymphatic channels
and metastasizes
to other areas of
the body
Benign and malignant tumor comparison
General effects
•Benign
•Is usually a localized
phenomenon that does
not cause generalized
effects unless its
location interferes with
vital functions
•Malignant
•Often causes
generalized effects,
such as anemia,
weakness, and weight
loss
Tissue destruction
•Benign
•Does not usually cause
tissue damage unless its
location interferes with
blood flow
•Malignant
•Often causes extensive
tissue damage as the
tumor outgrows its
blood supply or
encroaches on blood
flow to the area; may
also produce substances
that cause cell damage
Ability to cause death
•Benign
•Does not usually
cause death unless
its location
interferes with vital
functions
•Malignant
•Usually causes
death unless
growth can be
controlled
Nomenclature – Benign Tumors
•-oma = benign neoplasm
•Mesenchymal tumors
• chrondroma: cartilaginous tumor
• fibroma: fibrous tumor
• osteoma: bone tumor
•Epithelial tumor
• adenoma: tumor forming glands
• papilloma: tumor with finger like projections
• papillary cystadenoma: papillary and cystic tumor forming
glands
• polyp: a tumor that projects above a mucosal surface
Nomenclature – Malignant Tumors
•Sarcomas: mesenchymal tumor
•chrondrosarcoma: cartilaginous tumor
•fibrosarcoma: fibrous tumor
•osteosarcoma: bone tumor
•Carcinomas: epithelial tumors
•adenocarcinoma: gland forming tumor
•squamous cell carcinoma: squamous differentiation
•undifferentiated carcinoma: no differentiation
•note: carcinomas can arise from ectoderm, mesoderm,
or endoderm
