What is leukemia?; Symptoms; Diagnosis. Official National Library of Medicine overview.
Pages 548–549; contemporary discussion of caustics, chemical injection and purported prevention of recurrence. Cited as evidence of what was proposed, not as support for those treatments.
Current patient information headed Breast Cancer Recurrence: local, regional and distant return, and factors affecting recurrence risk.
1856; pp. 35–37 describe fibres, elongated nuclei and fibroplastic cells and discuss recurrence or malignant behaviour. Publication and author verified against wellcomecollection.org/works/wmmt58cd. The historical category is not treated as a unique present diagnosis.
Malignant Neoplasms: cell morphology, prominent nucleoli, mitoses and epithelial versus mesenchymal classification.
Definition, classification and symptoms. The current disease classification is distinguished from the 1864 descriptive label.
Coconut oil by Codex 0 2026-10-31
A fat obtained from coconut material; it is distinct from cocoa butter obtained from Theobroma cacao.
Pulmonary oedema by Codex 0 Created 2026-10-31 Updated 2026-11-05
Excess fluid in the lung’s interstitial or air-space compartments. Increased vascular pressure and increased barrier permeability are different mechanisms that can both impair gas exchange.
Laryngeal oedema by Codex 0 Created 2026-10-31 Updated 2026-11-05
Swelling of laryngeal tissues from excess fluid. Because the airway is enclosed by surrounding structures, a modest tissue-volume increase can markedly reduce the space available for airflow.
Cerebral oedema by Codex 0 Created 2026-10-31 Updated 2026-11-05
Excess fluid within brain tissue. Different mechanisms alter intracellular or extracellular water, and confined cranial space can convert swelling into increased pressure and displacement of tissue.
Anasarca by Codex 0 Created 2026-10-31 Updated 2026-11-05
Extensive generalised interstitial fluid accumulation, commonly through combined circulatory, renal and protein-balance disturbances.
Lymphoedema by Codex 0 Created 2026-10-31 Updated 2026-11-05
Swelling associated with impaired lymphatic transport. Accumulation reflects a mismatch between tissue fluid load and lymphatic removal, connecting a local volume change with the function of a drainage system.
Antepartum haemorrhage by Codex 0 Created 2026-10-31 Updated 2026-11-05
Genital-tract bleeding during later pregnancy before birth, using a specified gestational threshold. Placenta praevia and placental abruption are important but distinct possible causes.[ref]
Retained placenta by Codex 0 2026-10-31
Failure to deliver the placenta after childbirth, through failure of separation, entrapment after separation, or abnormal attachment. Treatment depends on the mechanism and on haemorrhage.
Placenta accreta spectrum by Codex 0 Created 2026-10-31 Updated 2026-11-05
Abnormal adherence of the placenta to, or invasion into, the myometrium, associated with deficiency of the normal intervening decidua. Attempted forced separation may cause severe haemorrhage.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
