Introduction
• Why we have to learn about cancer/ tumor?• Cancer is the second leading cause of death• In the year 2000,
–10 million new cases of cancer –6 million cancer deaths worldwide.
• In the United States 2003, –Cancer caused 556,000 death/year –1500 cancer deaths per day.

DEFINISI NEOPLASMAPertumbuhan baru dimana terdapat diferensiasi sel, maturasi dan kontrol pertumbuhan yang abnormal
Suatu massa jaringan abnormal yang tumbuh berlebihan dan tidak teratur di sekitar jaringan normal yang akan berlangsung terus walaupun rangsangan penyebab sudah hilang dan mengakibatkan timbulnya perubahan.(1954, Ruppert Willis)

• Neoplastic cells parenchyma.• Non-neoplastic - stroma (Connective
tissue & BV)
• Fast growth less stroma • Less stroma more necrosis
![Page 25: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/25.jpg)

• Cell of origin• Rate of growth• Differentiation• Local Invasion• Metastasis
• Lung cancer• Grade - low, high• Well, Mod, P, Un.• Staging• Staging
Lung cancer:Squamus cell carcinoma.Poorly differentiated, high grade, stage 4, Liver+
![Page 26: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/26.jpg)
Benign Malignant:• Slow growing,• capsulated, • Non-invasive • do not metastasize, • well differentiated, • suffix “oma” eg.
Fibroma.
• Fast growing, • non capsulated, • Invasive & Infiltrate • Metastasize. • poorly differentiated, • Suffix “Carcinoma” or
“Sarcoma”
![Page 27: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/27.jpg)
What makes a neoplasm “malignant” ?
• The ability to invade and/or metastasize.
• Examples: Basal cell carcinoma ( a skin neoplasm) invades but rarely metastasizes.
• Malignant melanoma of the skin invades and can widely metastasize.
![Page 28: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/28.jpg)
Language of Oncology
• Neoplasm: (meaning new growth that is “autonomous”); scientific term for a tumor.
• May be “malignant or benign”• Other “plasias”:
– Hyperplasia: an increase in cell number– Hypertrophy: an increase in cell size but not
number– Metaplasia: a reversible process where one cell
type changes into another cell type
![Page 29: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/29.jpg)
What Is Cancer?
CANCER is a complex of diseases which occurs when normal cells mutate into abnormal cells that take over normal tissue, eventually harming and destroying the host
![Page 30: Neoplasma 1](https://reader036.vdocuments.us/reader036/viewer/2022062303/556daaacd8b42a875d8b4cd3/html5/thumbnails/30.jpg)
WHAT IS CANCER
A large group of diseases characterizedby:– Uncontrolled growth and spread of abnormal
cells– Proliferation (rapid reproduction by cell division)– Metastasis (spread or transfer of cancer cells
from one organ or part to another not directly connected)

A. Cut section of an invasive ductal carcinoma of the breast. The lesion is retracted, infiltrating the surrounding breast substance, and would be stony hard on palpation.
B. The microscopic view of the breast carcinoma seen in A illustrates the invasion of breast stroma and fat by nests and cords of tumor cells. Note the absence of a well-defined capsule.

KARATERISTIK TUMOR JINAK & GANAS
Melalui Rongga Tubuh dan Permukaan Terjadi pada neoplasma ganas yang menembus ke dalam tempat yang terbuka / rongga kavum peritonium, pleura, perikardial, subarachnoid dan rongga sendiContoh: Ka. Ovarium pseudomiksoma peritonei
Melalui Pembuluh LimfeTransportasi melalui limfatik cara utama penyebaran karsinoma.Contoh: Ka. Mammae
Penyebaran HematogenCara ini spesifik untuk sarkoma. Arteri dengan dinding lebih tebal kurang cepat penetrasi dari pada vena

Benign and Malignant Tumor
Characteristic Benign Malignant
Differentiation Well differentiation, structure may be typical of tissue origin
Lack of differentiation/ anaplasiaStructure is often atypical
Rate of growth Usually progressive and slow growth,Mitotic figures are rare and normal
Erratic, may be slow to rapid,Abnormal and Numerous mitotic figure
Local invasion Usually well demarcated and no infiltration to the surrounding tissue
Locally invasive, infiltration to the surrounding tissue
Metastasis Absent Frequently present
