Types of cancer, tumor ,neoplasm | Treatment & Prognosis


This is an Introduction about Cancer/Tumor/Neoplasm. Types of cancer. Treatment & Prognosis of Cancer & Chemotherapeutic cancer agents.

Tumor/Neoplasm/Cancer


1) Definition: Tumor is an abnormal independent& purposeless growth of cellmass.

2) Types of Tumor:
a)Bening Tumor -Growth of cell mass can be stopped.
b)Malignant -in malignant Tumor growth of cell mass
continues & Proliferation is in an atypical way.

Difference between Bening & Malignant Tumor

Bening Tumor

1)Encapsulated,Well circumscribed.
2)Small size.
3)Pleomorphism absent.
4)Hyper chromatism absent.
5)Slow growth rate.
6)Metastasis absent.

Malignant Tumor

1)Poorly circumscribed.
2)Larger size
3)Pleomorphism present.
4)Hyper chromatism present.
5)Rapid growth rate.
6)Metastasis present.

3) Treatment & Prognosis:

1)Factors affecting prognosis.
a)Age.

b)Biology of Cancer.-1)Rapid growing-Squamous cell carcinoma of Lungs.
2)Slow growing- Papillary carcinoma of thryoid.

c)cell differentiation.
Grade1.
Grade2.
Grade3.
Grade4.

d)Distant Metastasis.TNM classification.

T-Tumor. N-Node. M-Metastasis.
No- No node. M0-No distant metastasis.
T1-Tumor < 2cm. N1-Movable node. M1-Distant Metastasis.
T2-Tumor 2-5 cm. N2-Fixed large node.
T3- >5cm.
T4-Tumor fixed to chest wall.

e)Host factor.
f)Site.
g)stage.

4) Principle of Treatment :

1)Eradicative.
2)Palliative.


Methods :

1)Surgery
2)Radiotherapy
3)Chemotherapy

5) Chemotherapeutic Cancer Agents :

1)ANTI METABOLITES.-They acts on Neuclotide.
eg.-5-flurouracil.(Pyrimide)

2)ALKALYTING AGENTS-They produce intranuclear tissue damage.
eg.-a)Cyclophosphamide. b)Nitrogen mustard gas.

3)ANTIBIOTICS--- They cause DNA destruction.
eg.-Actinomyocine-D.

4)ANTIMITOTIC AGENTS-They arrest cell division.
eg.-Vincristine.

Some Names & Examples of tumor.
1)Lipoma.-Fat cell tumor.
2)Osteoma.-Tumor arising from bone.
3)Neuroma.-Tumor of Nerve.

***IN SHORT***---- For tumor, in Ayurveda there is a good hope if Cancer is in the initial stage then there are more chances of recovery.

In Ayurveda the cancer is described as ARBUDA. There are lot of Ayurvedic Cancer Rehabilitation and research centres in Pune so it is a good hope for all Cancer patients.
