Summary
Abnormal nuclear DNA content and increased cell size in breast and gastric lesions indicate a high risk for future cancer development, requiring careful evaluation.
Area of Science:
- Cytopathology
- Oncology
- Histopathology
Background:
- Accurate assessment of cellular abnormalities is crucial for diagnosing breast and gastric lesions.
- Nuclear DNA content and morphometric variables are key indicators of cellular changes.
Purpose of the Study:
- To quantitatively evaluate nuclear DNA assessments and morphometric variables in breast and gastric lesions.
- To correlate these findings with the potential for malignancy.
Main Methods:
- Absorption cytophotometry was used to measure nuclear DNA content.
- A graduated eyepiece micrometer was employed for morphometric analysis.
- Cytologic smears and paraffin-embedded tissue sections were analyzed.
Main Results:
- Normal cells showed diploid-tetraploid DNA distributions.
- Hyperplastic processes and benign tumors exhibited aneuploidy with high DNA content (5C-hyperoctaploid).
- Carcinomas displayed DNA values up to 10-16C, with increasing morphometric data from normality to cancer.
Conclusions:
- Abnormally high DNA content and aneuploidy in hyperplastic lesions suggest potential malignancy.
- Increased morphometric measures correlate with the progression towards cancer.
- These findings highlight the importance of precise evaluation for early cancer risk detection.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:26Cellular Adaptation III: Hyperplasia
Hyperplasia is an increase in the number of cells in a tissue or organ due to enhanced cell division. It is an adaptive, controlled response to stimuli such as injury, hormones, or stress, involving mitosis to produce genetically identical cells and support tissue repair and regeneration.Tissue CapacityCertain tissues, including the epidermis, intestinal epithelium, bone marrow, and fibroblasts, have a high potential for hyperplasia. Others, such as bone, cartilage, and smooth muscle, show...
01:24Cellular Adaptation IV: Dysplasia and Metaplasia
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
