Presentation Transcript

Slide 1: 

CANCER A DISEASE OF THE GENOME PREPARED BY: Lonewalker

CONTENTS: : 

CONTENTS: A.INTRODUCTION TO TUMORS B.INTRODUCTION TO CANCER C.CAUSES OF CANCER D.SIGNS AND SYMPTOMS E.PREVENTIVE MEASURES F.DIAGNOSIS G.TREATMENT

Slide 3: 

TUMORS: ANY ABNORMAL SWELLING,LUMP OR MASS. NEOPLASM: THE SCIENTIFIC TERM TO DESCRIBE AN ABNORMAL PROLIFERATION OF GENETICALLY ALTERED CELLS. NEOPLASMS CAN BE BENIGN OR MALIGNANT.

Slide 5: 

BENIGN NEOPLASM OR BENIGN TUMORS: A TUMOR(SOLID NEOPLASM) THAT STOPS TO GROW BY ITSELF. DOES NOT INVADE OTHER TISSUES. DOES NOT FORM METASTASIS. MALIGNANT NEOPLASM OR MALIGNANT TUMORS: SYNONYMOUS WITH CANCER. CAN SPREAD FROM THE ORIGINAL BODY PART HAVING THE TUMOR TO THE OTHER PARTS AS WELL.

CANCER : 

CANCER Cancer (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood.)

Characteristics of cancer cell : 

Characteristics of cancer cell Self-sufficient growth signals Constitutively activated growth factor signalling Resistance to anti-growth signals Inactivated cell cycle checkpoint Immortality Inactivated cell death pathway Resistance to cell death Activated anti- cell death signalling Sustained angiogenesis Activated VEGF signalling Invasion and metastasis Loss of cell-to-cell interactions, etc.

Classification of cancer: : 

Classification of cancer: Carcinoma Sarcoma Lymphoma and leukemia Germ cell tumor Blastic tumor or blastoma

Causes of cancer : 

Causes of cancer Mutation: chemical carcinogens Mutation: ionizing radiation Viral or bacterial infection Hormonal imbalances Immune system dysfunction Heredity Epigenetics Oncogenes Tumor suppressor genes Clonal evolution

Slide 11: 

Mechanism for cancer

Signs and symptoms : 

Signs and symptoms Systemic symptoms Symptoms of metastasis Local symptoms

Preventive measures : 

Preventive measures Modifiable ("lifestyle") risk factors Diet Vitamins Chemoprevention Genetic testing Vaccination Screening

Diagnosis : 

Diagnosis Most cancers are initially recognized either because signs or symptoms appear or through screening blood tests, X-rays, CT scans and endoscopy. Cytogenetics and immunohistochemistry DNA Microarray-based Cancer Diagnosis

Treatment : 

Treatment Surgery Chemotherapy Radiation therapy Immunotherapy Monoclonal antibody therapy Angiogenesis inhibitors Hormonal therapy

Slide 18: 

“Illness is the night side of life, a more onerous citizenship. Everyone who is born holds dual citizenship, in the kingdom of the well and the kingdom of the sick. Although we all prefer to use only the good passport, sooner or later each of us is obliged, at least for a spell, to identify ourselves as citizens of that other place” Susan Sontag
