- breast: 1mm depth, 7mm width ovary: 3 mm depth, 10 mm area
- cervix: 5 mm depth, 7 mm area (FIGO); 3 mm depth (SGO)
- salivary carcinoma ex pleomorphic adenoma: @<@ 1.5 mm

Minimally invasive adenocarcinoma is defined as tumors with lepidic or predominantly lepidic growth, @<@= 3 cm in size, with @<@= 5 mm of invasion into the stroma.

- ovary

  • Mucinous and serous borderline tumors of the ovary with invasion @<@ 3mm and area @<@ 10 mm are considered borderline tumors.

- breast

  • @<@ 1 mm of invasion beyond the basement membrane is considered microinvasion in the breast.

- cervix

  • By FIGO (International Federation of Gynecology and Obstetrics) standards, invasive squamous cell carcinoma of the cervix @<@ 5 mm in depth and @<@ 7mm in width is consistent with microinvasive carcinoma.
  • The Society of Gynecologic Oncologists (SGO) characterizes microinvasion in the cervix as @<@ 3 mm depth.
