  The color of poop - a visual guide to the quiet warnings our bodies send 🟥 Red Possible cancers: • Colon cancer • Rectal cancer • Anal cancer Why it happens: Fresh blood mixes with stool when tumors in the lower GI tract bleed. Clue: Blood is on the stool or in the toilet bowl, not digested into it. ⚫ Black / Tarry Possible cancers: • Stomach cancer • Esophageal cancer • Small intestine tumors Why it happens: Blood from higher up in the GI tract gets digested, turning stool black and sticky. Clue: Looks like coffee grounds mixed with tar. 🟤 Dark Brown / Maroon Possible cancers: • Right‑sided colon cancer • Small bowel tumors Why it happens: Slow bleeding higher in the colon darkens stool without turning it fully black. Clue: Often overlooked because it still “looks like poop.” 🟡 Yellow / Greasy / Floating Possible cancers: • Pancreatic cancer • Ampullary cancer Why it happens: Tumors block pancreatic enzymes → fat isn’t digested → stool becomes oily, pale, ...

  (Sula in the arms of Fr. Ed at her godparents' house in Hollister, godparents on the left, friend on the right, and another MSI Press author, CB Leaver , in red in the front) Sula has been the parish cat at Old Mission San Juan Bautista for 13 years and through four bouts of cancer (fourth just starting/reappearing). With Covid-19 and the shutdown of the Mission, along with the rest of the state of California, Sula retired to live with her godparents in Hollister, where she can be watched after and can even have a visit occasionally frnom a retired priest from the parish who lives neaby. She still works on Sundays, though -- and visitors are always delighted to find her in the pews at Mass, where she goes on her own and sits with whomever seems to need her at the moment even though she does have her own pew with her name on it, and between Masses at the Mimssion gift shop. Here is her bio: Sula is a very unusual cat. She is the parish cat for Old Mission San Juan Bautista and, b...

  For years, alcohol carried a kind of health halo — especially red wine. But modern cancer research has stripped away the romance and left us with a clear, uncomfortable truth: alcohol is a carcinogen , full stop. Not just hard liquor. Not just “heavy drinking.” Any drink containing ethanol — beer, wine, cocktails — increases cancer risk. Why alcohol raises cancer risk When the body breaks down alcohol, it produces acetaldehyde , a toxic compound that: damages DNA interferes with DNA repair promotes inflammation disrupts hormone regulation (especially estrogen) Over time, these changes increase the likelihood that damaged cells will become cancerous. Which cancers are linked to alcohol? The list is longer than most people realize. Strong evidence connects alcohol to: Breast cancer (even at low levels) Colorectal cancer Liver cancer Esophageal cancer Head and neck cancers Stomach cancer (emerging evidence) There is no safe threshold . Even one drink a day nudges...

  Poop is one of the body’s earliest alarm systems, and different cancers can alter stool in different ways. Pencil‑thin stool is the classic red flag for colon cancer, but it’s far from the only pattern worth knowing about. The changes below come from how tumors block, bleed, or interfere with digestion and bile flow. 1. Colon & Rectal Cancer Why stool changes: Tumors narrow the passageway, bleed easily, or disrupt water absorption. Key stool patterns: Pencil‑thin or ribbon‑thin stool — narrowing from a tumor blocking the lumen. Pebble‑like hard pellets — obstruction causing excess water absorption. Blood in stool Bright red → lower colon or rectum. Black/tarry → bleeding higher up. Mucus in stool — especially with mucinous tumors. Alternating constipation and diarrhea — partial obstruction. 2. Pancreatic Cancer Why stool changes: Blocked bile duct → no bile reaching the intestine; lack of pancreatic enzymes → fat malabsorption. Key stool patterns: P...
